Integumentary System  Key Terms  derm/o - skin   kerat/o - hard, horn-shaped tissue  xer/o - dry  xanth/o - yellow  erythr/o - red  pedicu/o - fingernail, toenail  onych/o - nail  myc/o - fungus  pil/o - hair; hair follicle  lip/o - fat  rhytid/o - sebum which secretes oil  albin/o - white  Function  The integumentary system has four main functions. Protection, body temperature  maintenance, exertion, and perception of stimuli.  Protection: Physical barrier of underlying tissues to protect from physical damage,  ultraviolet rays, and pathogenic invasion.  Body Temperature Maintenance: Perspiration regulates the body’s natural temperature  3

Integumentary System  Exertion: Sweat glands also release waste products, containing, water, salt and organic  compounds  Perception of stimuli: Contains a large quantity of nerve endings that detect stimuli.  There are also tactile receptors that are responsible for touch.  Vocabulary  Albinism - Inflammatory disorder of the sebaceous glands that produce pimples on the  skin  Cicatrix - A scar left by a healed wound (lightened area on the skin).  Ecchymosis - Black-and-blue or purplish bruise caused by ruptured blood vessels  beneath the skin  Keloid - An abnormally raised, thickened scar.  Cyst - A closed, thick-walled sac or pouch containing fluid or semisolid material that  develops in a cavity or other structures in the body  Macule - Small, flat, discolored, lesion on the skin (freckle)  Papule - A solid skin elevation with distinct borders and a diameter less than one  centimeter (pimple)  Psoriasis - Chronic disease marked by itchy, erythematous skin with silver patches  Vitiligo - Loss of pigment in one or more areas of the skin, creating the appearance of  milky-white patches  Scabies - Contagious, parasitic infection of the skin with intense pruritus or itching      4

Integumentary System  Diseases / Disorders  Impetigo - Bacterial infection of the skin characterized by vesicles (small, fluid-filled  sacs), pustules (small, pus-filled blisters), and crusted-over lesions .  Gangrene - Necrosis or death of tissue, due to loss of blood supply, followed by a  bacterial infection.  Alopecia - Hair loss that results from genetics, normal aging, illness, or drugs used to  treat certain diseases.  Cyanosis - Appearance of blue/purple discoloration of the skin due to insufficient blood  oxygen or poor circulation. Many respiratory and circulatory diseases produce cyanosis.  Health Careers  Primary Care Physician (PCP) - A physician that gives the first contact of a person with  an undiagnosed health concern. Also, treats various medical conditions no matter the  cause.  Dermatologists - Medical practitioner ready to diagnose and treat the multitude of skin  disorders that may happen.  Labeled System    5

Musculoskeletal System  Key Terms  my/o - muscle  myel/o - bone marrow; spinal cord  oste/o - bone  cost/o - rib  crani/o - skull  -pexy - surgical fixation or suspension  chondr/o - cartilage  arthr/o - joint  -plegia - paralysis  kinesi/o - movement  Function  The skeletal system is made up of bones and other such things that provide a structure  for the body. Five important functions of the skeletal system are support, protection,  mineral storage, blood cell formation, and anchoring and movement of muscle.  Support: Provides the shape and structure for the body.  Protection: Surrounds and protects the internal organs from damage.  Mineral Storage: Phosphorus and calcium are two necessary minerals for regulatory  functions, which are stored inside of the bones.  Blood cell formation: Inside of the bone marrow, red blood cells are constantly being  made.  6

Musculoskeletal System  Anchoring and movement of muscle: For muscular movement and action, the bones are  the supporting structures.  The muscular system is composed of various amounts of tissue that interact with each  other to execute essential functions of the body. Examples include permitting  movement to be possible, along with holding the body parts in position. It is also a  protective mechanism for internal organs. Transports the food through the digestive  tract. Helping blood flow throughout the body in order to return to the heart.  Vocabulary  Ataxia - Inability to coordinate voluntary muscle activity; characterized by shaky,  unsteady movements.  Bursa - Enclosed sac filled with viscous synovial fluid and are located in areas of  possible friction to help muscles and tendons glide smoothly over bone  Bulge Sign - Distinct bulge observed from a synovial fluid wave in the medial aspect of  the knee after displacing the fluid and tapping on the lateral aspect   Contracture - Shortening of a muscle leading to limited ROM (range of motion) of a joint  Dislocation - When a bone is out of a socket  Epiphysis - Growth plates in long bones where lengthening occurs  Hematopoiesis - Red blood cell production in the bone marrow  Hypertrophy - Excessive growth or abnormal enlargement of a muscle  Shin Splint - Painful condition caused by muscle tearing away from the tibia  Tremor - Involuntary, repetitive shaking or quivering of a part or parts of the body.  Diseases / Disorders  Ankylosis - A stiff joint caused by adhesion, or abnormal fusion of two bones into one  bone  7

Musculoskeletal System  Muscular Dystrophy (MD) - Genetic disease characterized by progressive muscular  weakness and skeletal muscle deterioration   Myeloma - Cancer of the plasma cells (type of white blood cell) that originates in the  bone marrow  Myasthenia Gravis - Chronic autoimmune disease characterized by voluntary muscle  weakness that worsens after activity and improves after rest  Leiomyoma - Benign tumor of smooth muscle, such as that found in the heart, bladder,  or uterus.  Healthcare Careers  Neuromusculoskeletal Medicine Doctor - Specialist in osteopathic medicine, doctors  who become experts in the diagnosis and treatment of musculoskeletal and related  neurological medical problems   Orthopedic Doctor - Devoted to the prevention, diagnosis, and treatment of disorders of  the bones, joints, ligaments, tendons, and muscles.  Labeled System    8
