muscle/joint sensation

Question 1

role of propioceptors

Answer 1

detect position and movement
prevent damage from overstretching or over-contracting
scattered throughout skeletal muscle

Question 2

what is a motorneuron pool?

Answer 2

set of motorneurons innervating fibers within the same muscle

Question 3

pattern between motor neuron size and force:

Answer 3

smaller motor neurons –> lower threshold –> fewer fibers –> fire first –> less force generated

larger motor neurons –> greater threshold –> more fibers –> fire later –> more force generated

Question 4

kinesthetic sense:

Answer 4

keeps track of body parts in relation to each other
provides constant sensory feedback about what your muscles are doing

detected via autonomic receptors

Question 5

two types of muscle receptors

Answer 5

muscle spindles
golgi tendon organs

Question 6

what are golgi tendon organs?

Answer 6

receptors located in the muscle tendons and transmit info about tension rate and changes in tension

prevents the tendon from tearing or detaching from the bone

Question 7

golgi tendon structure:

Answer 7

sensory nerve endings interwoven between collagen fibers with an afferent neuron emerging from the structure (to transmit info)
