rigid matrix composed of inorganic salts (calcium), living tissue that supports the body, proficient movement, produce blood cells
process of being broken down and rebuilt, result of two processes, stronger bones with use
bone matrix becomes weaker, breakdown of the mineral and protein content of bone matrix
covers surfaces of joints, forms the framework for the lower respiratory tracks and becomes harder with age.
connects or bind structures in order to support the body and aids in certain matinence in the body
parallel fibers (run int he same direction) that have elastic fibers embedded in them, makes them suitable for connecting bones to bones, bones to carts, and carts. to carts.
parallel fibers, closely packed (dense) and non elastic. Always ass. with a muscle mech.: in which most muscles attach to bones, sometimes attach bones to carts. and mus. to mus.
Voluntary muscle fibers, you continuously move the muscles. Volitional control can override the reflexes
the names of the muscles describe the muscle in some way. ex- Digastricus (two bellied)
The muscles may be named according to which bones the muscles are attached (ex.-sternocleidomastoid)
the function of the muscle may be described (ex.- Tensor tympani- makes the eardrum tight, tense)
decline in muscle tension, as a result of previous activity slower rate of relaxing, how quickly you fatigue and rate of fatigue dependent on the muscle fiber and the intensity of the fiber
lines most of the body's surfaces, and protects other tissues from damage/dehydration
Functional layer of the skin that lies just beneath the epidermis, contains nerve cells, blood vessels, and hair folicals.
single layer of flattened cells, found in blood vessel walls; air sacs of lungs. Function: Diffusion
single layer of cubelike cells; may have microvilli at its free surface, part of the gut lining, part of respiratory tract lining
single layer of tall, slender cells; may have microvilli at its free surface, part of gut lining and respiratory tract
variation of the cuboidal cell, also found in the res./dig tracts. Designed to secrete mucin (type of mucus)
points of articulation in the body: some have high mounts of movement, some have low, and some have none at all
Ball and socket
joint that consists of a rounded ball like and that ifts into a cup like cavity shoulder hip
pivot is between the effort and the load, ROM and speed are attained at the expense of power (allow for greater power, giving up your speed and range of motion)
fulcrum (joint) is at one end of the lever arm (bone) and the force applied. (the muscle attachment is at the other end and the load is in between) *jaw opening against resistance, allows little people to move big things.
