Study Notes

Neuroanatomical Terms and Conventions

Tracts are bundles of axons in the CNS (white matter)
Nerves are bundles of axons in the PNS
Nuclei are groups of neuron cell bodies in the CNS (grey matter)
Ganglia are groups of neuron cell bodies in the PNS
Planes of view include sagittal, coronal, and horizontal

Planes of View

Horizontal plane: a slice parallel to the brain's normal orientation
Sagittal plane: a slice from the front of the forehead to the back; if it's through the middle, it's called the midsagittal view (provides the most visualization to whole brain structures), aka medial view.
Coronal plane (coronal = crown): a great view for visualizing different structures within the brain

Divisions of the Brain

Forebrain: subdivided into telencephalon and diencephalon
Telencephalon contains the cerebral cortex, limbic system, and basal ganglia
Diencephalon contains the thalamus and hypothalamus
Midbrain: contains superior and inferior colliculi
Hindbrain: contains the medulla, pons, cerebellum, and reticular formation

Development of the Nervous System

Ectoderm is the source of the nervous system
The ectoderm thickens to form a neural plate, then a neural groove
The neural groove edges fuse to form the neural tube
Neural crest cells develop into the PNS

Development of Neural Tube

The neural tube forms the CNS
Neural crests form the PNS
Embryonic vesicles develop into the forebrain, midbrain, and hindbrain

Functions of Hindbrain Regions

Medulla controls vital functions like heart rate, blood pressure, and respiration
Pons connects the brainstem with the cerebellum and is involved in alertness and consciousness
Cerebellum coordinates movement and balance
