Pre-ganglionic neurons of the autonomic nervous system are located in

Both the brainstem and lateral grey horns of the spinal cord

The blank reflex complements the flexor reflex by activating contralateral muscles

Crossed extensor

Sensory information from all parts of the body is routed to

The somatosensory cortex

Ganglionic neurons innervate

Glands, smooth muscle, cardiac muscle, adipose tissue

splanchic nerves

Innervate the viscera or internal organs

In order to take notes the primary motor cortex must receive input from the blank first

Premotor cortex

Action potential's from receptors involved in general sensations are interpreted in the

Primary sensory cortex

Sweat gland

The blank nervous system stimulates the arrector Pillai muscles and give you goosebumps

Sympathetic

A pedestrian narrowly avoided being hit by an oncoming car, he noticed that it takes a little while for his heart rate and respiratory rate to return to normal, this is likely because
