Test 2 - Skelteal System Flashcards
Tissue Types - Epithelial
lines cavities, cover surfaces
Tissue Types - Connective
GPS
ground substance
proteins
specialized cells
Tissue Types - Muscular
moves other body tissues
Tissue Types - Nervous
conducts electrical signals
Functions of Bones - Movement
bones interact with skeletal muscles to maintain or change the position of body parts
Functions of Bones - Support
bones support and anchor muscles
Functions of Bones - Protection
many bones form hard compartments that enclose and protect soft internal organs
Functions of Bones - Mineral Storage
bones are a reservoir for calcium and phosphorous, deposits/withdrawals of mineral ions maintain proper concentrations in body fluids
Functions of Bones - Blood Cell Formation
some bones contain marrow where blood cells are produced
Movements of the Body
flexion: decrease in joint angle
extension: increase in joint angle
hyperflexion: moving past normal amount of flexion
Integumentary System
skeleton provides support
for skin and the muscles below it.
Muscular System
skeletal muscles attach to bones, which serve as levers for body movements
bone calcium may be released as needed to maintain blood levels required for muscle contractions.
The skeleton provides support
for skin and the muscles below it.
Respiratory System
rib cage and sternum protect the lungs, muscles used in breathing attach to ribs and associated cartilages
Urinary System
rib cage partially protects the kidneys, pelvis helps protect the bladder
Nervous System
skull protects the brain, vertebrae protects the spinal cord
bone calcium stores may be
released as needed to maintain blood levels required for transmission of nerve impulses
