Shwann cells vs Oligodendrocytes
White matter and gray matter
Myelin Staining in the Spinal cord
A brief Consideration of the PNS; an artificial division
The vertebral column
Each vertebra houses a spinal cord segment
Each segment is similar
Dorsal = sensory Ventral = motor
Each segment gives rise to nerve pairs
And the column collectively gives rise to 30 peripheral nerve pairs
Each nerve pair contains thousands of incoming and outgoing axons
The Somatic Branch of the PNS - Provides all somatosensory information to the central nervous system (brain)
Sensory dermatomes
The Somatic Branch of the PNS relays motor output to skeletal muscles (Not smooth muscle)
The other subdivision of the PNS-the ANS
Sympathetic activation may be magnified by adrenal gland
THE CNS
