Question 15

Direction of Efferent nerves

Answer 15

bring signals from CNS to organs and muscles

Question 16

Answer 16

bring signals from organs and muscles to CNS

Question 17

describe reflex arc

Answer 17

stimulus hitting tendon, then the muscle contracts which jerks the foot. Stimulus is detected by sensory receptors which send a message to the sensroy neuron and then to interneurons. Interneurons transmit the message to a motor neuron which causes the muscle to contract. The reflex does not even go up to the brain, just through the spinal cord

when do action potentials happen

Answer 18

when the neuron is stimulated past the necessary threshold

a neurotransmitter is released to affect the adjoining cell

Answer 20

nodes of ranvier

Question 21

what are the axons insulated by

Answer 21

oligodendrocytes and the myelin sheath
