Study Notes
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
- CNS includes the brain and spinal cord
- PNS encompasses all other parts of the nervous system outside of the skull and spinal column
Nervous System Components
- Nerves: bundles of axons located outside the CNS
- Somatic nervous system: connects the brain to major muscles and sensory systems
- Autonomic nervous system: controls internal organs (viscera)
- Enteric nervous system: local network of neurons governing gut function
Cranial and Spinal Nerves
- Cranial nerves: 12 pairs emerging directly from the brain (including the brainstem)
- Spinal nerves: 31 pairs emerging from the spinal cord, connecting it to the body
Autonomic Nervous System Divisions
-
Sympathetic nervous system: prepares the body for action (fight or flight)
- Increases blood pressure, heart rate, and pupil dilation
- Parasympathetic nervous system: often acts in opposition to the sympathetic system (rest and digest)
Brain Planes
- Horizontal plane: divides the brain into an upper (dorsal) and lower (ventral) part
-
Sagittal plane: divides the brain into right and left halves
- Medial: towards the midline
- Lateral: away from the midline
- Midsagittal: directly in the center/middle
- Coronal plane: divides the brain into front (anterior) and back (posterior) regions
Brain Tissue
-
White matter: primarily composed of axons with white myelin sheaths
- Fiber/Tract: a bundle of axons
-
Gray matter: contains more cell bodies and dendrites, which lack myelin
- Nuclei: a collection of neurons
Meninges
- Dura mater: tough outermost layer, Latin for "tough mother"
-
Arachnoid: middle layer, resembles a spiderweb, cushions the brain
- Latin for "spiderweb-like"
-
Pia mater: delicate innermost layer, adheres to the brain
- Latin for "tender mother"
