22
Q

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

A

muscle spindles

23
Q

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

A

mm length and rate of change of mm length

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

24
Q

Muscle spindle action on mm

A

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

25
Q

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

A

Golgi tendon organs

26
Q

this fibers inhibit muscle action

A

Golgi tendon organs

27
Q

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

A

motor cortex

28
Q

area of sarcomere containing the z-line and actin

A

I-band

29
Q

area of sarcomere containing only myosin

A

h-zone

30
Q

area of the sarcomere containing both myosin and actin

A

A-band
