Module 1 Test Study Guide

Thoracic and lumbar

Spinal cord regions containing the preganglionic sympathetic neurons

Frontal lobe

Emotion, thinking, reasoning, personality, movement

Temporal lobe

Audition and memory

Parietal lobe

Somatosensory, memory, sense integration

Occipital lobe

Vision

Oligodendrocytes

Only in CNS, myelinates, can do several

Astrocytes

Ionic balance and pH, BBB, clean-up

Ependymal cells

Ventricles in brain and canal of spinal cord, CSF

Microglia

Monitor environment, immune response, phagocytic

Schwann cells

PNS, myelinates but only 1

Endothelial cells

Capillary wall

Pericytes

surround capillary wall, secrete for basement membrane, phagocytosis

Astrocytes in the BBB

in contact with basement membrane

Basement membrane

surround endo and peri; collagens, laminin, glycoproteins

Lipid soluble molecules

readily cross barrier

Charged molecules

impeded by barrier

Sugars

exception-crosses through BBB

Brainstem and Sacral

the majority of parasympathetic nervous system’s nerves

Choroid plexus

site of CSF production

Arachnoid granulations

site of CSF removal

Unipolar neuron

Single projection both axon and dendrite

Bipolar neuron

Dendrites look like it has an axon, common sensory

Pseudo unipolar neuron

2 axons, peripheral and central axons. Cell body sticks off like a skin tag

Multipolar neuron

Most common, poster child of neurons
