BioPsych Spinal Chord and Major Divisions of the brain

It communicates with all of the sense organs and muscles except the those of the head.

• Spinal Cord

• Cerebrum

• Amygdala

• Brain Stem

is a segmented structure and each segment has on each side a sensory and motor nerve.

• Brain

• axon

• Amydala

• Spinal cord

The entering dorsal roots (axon bundles) carry sensory information, and the exiting ventral roots carry motor information. What law is this?

• Bell Magendie Law

• Belle Magindy Law

• Frey Cerry Law

The axons from the skin and muscles are the

• Peripheral Nervous System

• Central nervous system

• Somatic nervous System

• Autonomic Nervous System

The cell bodies of the sensory neurons are in a cluster of neurons outside the spinal cord is called the

• Vertical root Ganglia

• Horizontal Root ganglia

• dorsal root ganglia.

• ventral root ganglia

The H shaped gray matter in the center of the cord is densely packed with cell bodies and dendrites.

• True

• False, T Shaped

Many neurons of the spinal cord send axons from the gray matter to the brain or other parts of the spinal cord through the white matter

• True

• False

Many neurons of the spinal cord send axons from the gray matter to the brain or other parts of the spinal cord through the white matter which consists mostly of

• myelinated axons

• Dendrites

• Soma

• Myelinated dendrites

is the lowest portion of the brain where the spinal cord rises to meet the brain

• The Hindbrain

• The Midbrain

• The forebrain

• The Migraine

Important structures of the hindbrain are

• cerebellum

• pons

• medulla

• nigra
