Cosmetologists - T hey work in the health and beauty field, taking care of client’s skin, hair and nails. The median wage is about $22,500, in order to become a cosmetologist, one must be a state-licensed barber or in school and be at least 16 years old.
M usculoskeletal The body system that provides support, stability, shape, protection and movement to the body. The muscular system specifically helps holding body parts in position, producing heat that keeps the body warm, moving food through the digestive system and aiding blood flow through the veins. The skeletal system specifically helps in the storage of minerals like calcium and phosphorus, and the formation of red blood cells in the bone marrow. Terminology: crani/o - skull -plegia - paralysis -pexy - surgical fixation kinesi/o - m ovement my/o - muscle myel/o - b one marrow chondr/o - cartilage oste/o - b one arthr/o - joint cost/o - rib Vocabulary: Voluntary muscle - Muscle that can be consciously controlled. Involuntary muscle - M uscle that is controlled by the autonomic nervous system (not consciously controlled). Skeletal Muscle - This muscle is a voluntary muscle that is attached to bone and can be contracted or relaxed through conscious control. Smooth Muscle - This muscle surrounds internal organs and is found throughout our respiratory tract, stomach, intestines, and urinary tract. Smooth muscle contracts and relaxes to movecontent through body system passageways. Tendon - T his is a band of fibrous tissue that connects muscle to bone. Cartilage - S oft connective tissue found between joints. Sesamoid bones - They facilitate joint movement and are found in patella(kneecap)and the hands, wrists, and feet. Ligaments - C onnective tissue that attaches bone to bone at a joint. Flat bones -These bones protect vital organs and provide a broad surface area of muscle attachment. An example Of Flat Bone is The Cranium. Hematopoiesis - This is the process of producing platelets, red and white blood cells in the bone marrow. Diseases/Abnormal Conditions: Arthritis - It is the inflammation of joints; usually accompanied by pain and, frequently, structural changes bone and cartilage. Spina Bifida - Split spine; congenital defect in which part of the membrane covering the spinal cord protrudes through a gap in the spine. Duchenne Muscular Dystrophy(DMD) - P rogressive disease that weakens the muscles of the shoulder and pelvic girdle. Myasthenia gravis - C hronic autoimmune disease characterized by voluntary muscle weakness that worsens with activity and improves with rest. Health Careers: Orthopedic Surgeon - This is a branch of medicine focused on treating or correcting musculoskeletal conditions, including spine and joint injuries or deformities. Orthopedic surgeons are physicians who specialize in diagnosis and treatment of spinal disorders, sports injuries, arthritis, and fractures. Orthopedic surgeons must hold a Medical Doctor(MD) or a Doctor of Osteopathic Medicine(DO) degree. Sports Medicine Physician - A sports medicine physician treats and prevents sports-related injuries of the bones, joints, and muscles. These health care professionals are qualified to diagnose and treat patients, prescribe medication and therapy, and perform surgery. They attend an accredited medical school to obtain a Medical Doctor(MD)degree or Doctor of Osteopathic Medicine(DO)degree.
Nervous System The Nervous System Has Three Main Functions, which include the sensory input, integration, and motor output. Terminology: n eur/o - n erve e ncephal/o - b rain myel/o - b one marrow -esthesia - feeling; sensation concuss/o - shaken together ambul/o - w alking psych/o - m ind mening/o - meninges Vocabulary: Neurons - Also called nerve cells, they are the fundamental cells of the nervous system. They are responsible for conducting electrical impulses throughout the body. Neuroglial Cells - c ommonly called glial cells, are specialized cells that support the vital functions of the nervous system. Neuroglial cells provide protective insulation for the neurons. Gray matter - This is an unmyelinated nerve tissue that is composed mostly of nerve cell bodies and dendrites. White matter - contains myelin sheaths,which shroud axons and made by neuroglial cells. Brain - It is the center of mental functions such as thinking, reasoning, remembering, planning, and expressing emotion. The brain controls voluntary muscular movement and regulates involuntary, life-sustaining processes. Brain stem - located beneath the diencephalon, connects the cerebrum with the spinal cord. It helps regulate the central nervous system by serving as a conduit for sensory information carried between the cerebrum or the cerebellum and the rest of the body. Effectors - The CNS transmits messages to the effectors, these are muscles or glands in the body that generate a response in the form of motor output. Electrochemical Signaling - This is the process of impulse transmission via the neurons, whi8ch is used to transmit electrical impulses from the brain and spinal cord and help to communicate to other parts of the body. Central Nervous System(CNS) - It comprises of the brain and the spinal cord. The CNS receives, processes, and responds to impulses from all over the body. It constantly monitors internal and external environmental stimuli. Peripheral Nervous System(PNS) - It is made up of nerves that reach into and extends from the brain and the spinal cord. The PNS functions as the liaison between the central nervous system and the rest of the body. Diseases/Abnormal Conditions: Alzheimer’s disease(AD) - A Form Of Dementia resulting from atrophy of the frontal and occipital lobes of the brain. Cerebrovascular accident(CVA) - Death of brain tissue that occurs when an arterial blockage or arterial rupture prevents blood flow to the brain; commonly called stroke. Dementia - A condition of progressive mental deterioration caused by organic brain disease. Characterized by memory loss, difficulties with language expression, etc. Myasthenia Gravis (MG) - A disease of the skeletal muscles caused by disruption in neural communication between the muscles and the nerves; marked by severe weakness and fatigue. Health Careers: Neurologist - A neurologist is a medical specialist that focuses on the functions and disorders of the nerves and brain, collectively known as the nervous system. Specifically, neurologists are tasked with researching illnesses and disorders, helping patients find solutions to neurological impairment, and exploring treatment and prevention strategies. Neuroscience Nurse - This person is a nursing professional that helps patients suffering from neurological problems. This can include injuries, such as head and spinal trauma from accidents, or illnesses, such as Parkinson's disease, meningitis, encephalitis, epilepsy, and multiple sclerosis.
Special Senses These senses monitor stimuli, or changes in the external or internal environment. When neural receptors are activated in the special sense organs, a neural impulse is transmitted to the brain. Terminology: ot/o - ear t ympan/o - eardrum (tympanic membrane) irid/o - iris ophthalm/o - eye -cusis - hearing -opia - v ision condition -metry - process of measuring Vocabulary: Sclera - Commonly known as the “white of the eye,” it is the fibrous outer layer of the eye that maintains the eye’s shape and protects the delicate inner layer of tissue. Aqueous humor - a clear, watery fluid called aqueous humor, which gives the eyeball its shape. The aqueous humor cleanses the eye and provides nutrients to both the cornea and lens, which lack their own nutritive blood supply. Auditory Canal - also called the external acoustic meatus. The auditory canal is a short, narrow chamber that leads to the tympanic membrane; it is about one inch long and one-quarter inch wide. Cochlea - a snail-like structure of the inner ear, contains special fluids called perilymph and endolymph, through which sound vibrations travel. The cochlea is also the site of the highly sensitive organ of Corti, which is integral to sound-wave conversion. Olfactory Hairs - Also called cilia; The ciliary apparatus is connected to cell cycle progression and proliferation, and cilia play a vital part in human development. Olfactory Bulb - the structure in the brain where olfactory nerves originate and where information about odors is processed. Taste Buds - They are tiny, sensitive, bulb-like structures that allow you to distinguish different tastes and textures as food moves across your tongue. The oral cavity is filled with thousands of taste buds, and most of these are on your tongue. Gustatory Sense - Commonly known as the sense of taste, encompasses five basic taste sensations: sweet, sour, salty, bitter, and umami. Specialized Nerve fibers - located in the dermis of the skin act as sensory receptors for pain, temperature, pressure, and touch. Epidermis - This forms the outermost layer of the skin. The epidermis is divided into layers of epithelial tissue, and nerve endings. Diseases/Abnormal Conditions: Vertigo - S ensation of irregular or whirling motion, of body or external objects, due to severe disturbance of equilibrium organs in the labyrinth. Hemianopia - Loss of one half of the visual field (the space of vision of eye). Dysgeusia - Condition in which the gustatory sense is impaired, resulting in one of two responses: an unpleasant taste sensation where previously the taste sensation was pleasant. Hyposmia - An Abnormally Weakened Sense Of Smell. Health Careers: Ophthalmologist - These professionals perform eye exams and diagnose various eye diseases and impairments. Ophthalmologists also prescribe glasses, contact lenses, or medication to treat eye conditions. Ophthalmologists have the additional responsibility of performing surgeries to correct eye conditions. Audiologist - This is a specialist who works with hearing, balance, and related disorders. Audiologists test patients for hearing loss. They determine whether someone can hear with in the normal range, and if not, which portions of hearing are affected and to what degree.
