Anatomy&physiology B

Front 1

Neuroglia

Back 1

(glial cells) play a major role in support and nutrition of the brain, but they do not manipulate information. They maintain the internal environment so that neurons can do their jobs.

Front 2

PNS

Back 2

it is consits fromganglia, enteric plexuses, and sensory receptors.

Front 3

CNS

Back 3

Most signals that stimulate muscles to contract and
glands to secrete
originate in the

Front 4

Somatic sensory (afferent)

Back 4

neurons that convey
information from sensory receptors in the head, body wall and limbs towards the CNS.

Front 5

Somatic motor (efferent)

Back 5

neurons that conduct impulses away from the CNS towards the skeletal muscles under voluntary control in the periphery.

Front 6

An autonomic
nervous system
(ANS)

Back 6

Sensory neurons that convey information from autonomic sensory receptors located primarily in visceral organs like the stomach or lungs to the CNS Motor neurons under involuntary control conduct nerve impulses from the CNS to smooth muscle, cardiac muscle, and glands.

Front 8

SNS consist Somatic nervous system

Back 8

Somatic sensory (afferent) neurons and Somatic motor (efferent) neurons

Front 9

Motor part of ANS

Back 9

two branches which usually have opposing actions:
•The sympathetic division
•The parasympathetic division

Front 10

ENS

Back 10

the “brain of the gut”, involuntarily controls GI propulsion, and acid and hormonal secretions.

Front 11

Ganglia

Back 11

are small masses of neuronal cell bodies located outside the brain and spinal cord, usually closely associated with cranial and
spinal nerves.
