NUTS AND BOLTS to get started

Location Terms Superior-inferior Medial- lateral Dorsal-ventral Rostral-Caudal…Anterior/Posterior

Planes of orientation

Dorsal Fin

The basic unit of the nervous system

White matter and gray matter

Staining for myelin in the brain coronal section

Staining for cell bodies in the brain-coronal section

Let’s begin with the PNS

The vertebral column

Each segment is similar

Dorsal = sensory Ventral = motor

Each vertebra houses a spinal cord segment

And the column collectively gives rise to 31 peripheral nerve pairs

Each nerve pair contains thousands of incoming and outgoing axons

motor output to skeletal muscles

And somatosensory input

The other subdivision of the PNS-the ANS

The sympathetic chain

Sympathetic activation may be magnified by adrenal gland
