Full Section 3 Flashcards
Muscle spindles
Sensory receptors sensitive to change in length of the muscle and the
rate of that change.
Golgi tendon organ
A specialized sensory receptor located at the point where skeletal
muscle fibers insert into the tendons of skeletal muscle; sensitive to
changes in muscular tension and rate of tension change.
3 Stages of Motor Development
- During stage 1 (cognitive), you may need to use simple instructions and break down the skill into smaller steps so your clients will be
able to understand the goals of the movement. - During stage 2 (associative), you may need to help refine your
clients’ skills through practice and regular feedback. - During stage 3 (autonomous), you may be able to teach your clients
new versions of the skill to further challenge them.

When a person loses body weight, what is the only way that mass is lost?
As metabolism converts food and stored tissue to ATP, carbon dioxide is formed as the main waste product. The body then exhales that CO2, and the energy once contained in stored body mass is released back into the environment within the CO2’s molecular bonds.
