Grey matter contains cell bodies and dendrites, while white matter consists of myelinated axons forming tracts. 3. Major Brain Divisions
Every "neuroanatomy notes PDF" starts with the building blocks:
Support cells such as astrocytes, oligodendrocytes (myelin in CNS), Schwann cells (myelin in PNS), and microglia. neuroanatomy notes pdf
Controls voluntary movements and transmits sensory information from the skin and joints.
The nervous system is anatomically divided into two primary parts: Grey matter contains cell bodies and dendrites, while
Comprises the brain and spinal cord .
The primary signaling units, consisting of a cell body (soma) , dendrites (receiving signals), and an axon (transmitting signals). oligodendrocytes (myelin in CNS)
Regulates involuntary functions like heart rate and digestion, subdivided into the Sympathetic and Parasympathetic branches. 2. Microscopic Neuroanatomy: Cells and Signaling
