Advanced Anatomy and Physiology: Nervous System

A set of flashcards covering key concepts and vocabulary related to the nervous system and neuroanatomy as discussed in the lecture notes.

Ganglia

Small masses of nervous tissue containing primarily cell bodies, located outside of the brain and spinal cord.

Neuroglia

Supporting cells in the nervous system that provide structure and support to neurons.

Oligodendrocytes

Neuroglial cells that form the myelin sheath in the Central Nervous System (CNS).

Microglia

Type of neuroglial cell similar to phagocytes; responsible for cleaning up debris in the nervous system.

Astrocytes

Neuroglial cells that support neurons and make up the blood-brain barrier.

Ependymal Cells

Cells found in the choroid plexus that line the ventricles of the brain and produce cerebrospinal fluid.

Schwann's cells

Neuroglial cells that form the myelin sheath in the Peripheral Nervous System (PNS).

Satellite cells

Support cells in the PNS that maintain the environment around neurons.

Leakage Channels

Non-gated channels that are always open in most cells.

Membrane permeability

Refers to the ability of the cell membrane to allow ions like K+ to pass through, often higher for potassium ions.
