Skeletal muscle reflexes

Question 1

what do the receptors sense in sk muscles?

Answer 1

changes in joint movements, muscle length, and tension–>feeds into CNS

Question 2

how does CNS stimulate muscle contraction?

Answer 2

CNS activates motor neurons

Question 3

how does CNS create relaxation?

Answer 3

activates inhibitory interneurons which relax the muscles–>protective mechanism to prevent extreme muscle damage

Question 4

components of sk muscle reflexes

Answer 4

1. sensory receptor; 2. integrating centre; 3. efferent neurons (alpha motor neurons); 4. effectors

Question 5

what is the purpose of proprioceptors?

Answer 5

Provide informa6on into the CNS about the posi6on of our limbs in space, movements, and the effort exerted by skeletal muscles

Question 6

golgi tendon organ and muscle spindles send info about length of muscles and tension in the muscles

Answer 6
