Question 22

proprioceptors that consist of several modified muscle fibers enclose in a sheath of connective tissue

Answer 22

muscle spindles

Question 23

Muscle spindle provide what information

Also they have what type of fibers in them and what direction do they run compared to other mm fibers

Answer 23

mm length and rate of change of mm length

These modified fibers, called intrafusal fibers, run parallel to the normal, or extrafusal, fibers.

Question 24

Muscle spindle action on mm

Answer 24

A simple example of muscle spindle activity is the knee jerk reflex - makes the knee contract during reflexes

responds to a stretch stim by contracting thus causing other fibers in mm to contract

Question 25

proprioceptors located in tendons near the myotendinous junction and are in series, that is attached to the end of extrafusal muscle fibers

Answer 25

Golgi tendon organs

Question 26

this fibers inhibit muscle action

Answer 26

Golgi tendon organs

Question 27

the ability of this area to override GTO inhibition may be on the the fundamental adaptations to heavy resistance training

Answer 27

motor cortex

Answer 28

I-band

Question 29

area of sarcomere containing only myosin

Answer 29

h-zone

Question 30

area of the sarcomere containing both myosin and actin

Answer 30

A-band
