nerves 3

Answer 13

whitish cords made of bundle of nerve fibres held together by connective tissue

where impulses are transmitted

originate in brain and spinal cord and branches to all parts of the body

Question 14

types of nerves 2

Answer 14

sensory nerves

motor nerves

Question 15

sensory nerves 3

Answer 15

carry impulses/messages from sense organs to brain where sensations are experienced

receptors

impulses pass through sensory nerves, to brain and back through motor nerves to muscle as complete circuit= muscle movement

Question 16

motor nerves 2

Answer 16

carries impulses from brain to muscles/glands

produce movement

Question 17

reflex 1

Answer 17

automatic nerve reaction to stimulus that involves movement of an impulse from sensory receptor to spinal cord and responsive impulse along motor neuron to muscle - causing reaction
