Posterior end of neural tube becomes the..
Spinal Chord
Neural tube establishes the anterior–posterior dimension of the nervous system
Neuraxis
Major curve between the brain stem and forebrain
Cephalic Fixture
Major portion of the human brain
Cerebrum
midbrain, hindbrain (pons, and medulla)
Brain stem
4 Major Lobes
1) Temporal 2) Parietal 3) Frontal 4) Occipital
Separates the parietal and frontal lobe
Central Sulcus
Major structures of the basal nuclei that control movement
caudate, putamen, and globus pallidus,
(except for smell) the rest of the brain, the spinal cord, and the PNS all send information to the cerebrum through this. It is made of the thalamus and hypothalamus.
Diencephalon
It is a requisite synapse in any sensory pathway, except for olfaction
Thalamus
a collection of nuclei that are largely involved in regulating homeostasis
Hypothalamus
largely responsible for comparing information from the cerebrum with sensory feedback from the periphery through the spinal cord.
Cerebellum
Connect through the brain stem and provide the brain with the sensory input and motor output associated with the head and neck, including most of the special senses.
Cranial Nerves
controls the function of most other endocrine glands
Pituitary Gland
Has role in sensory function, including hearing and vision; also important in memory
Temporal Lobe
Main connection with the cerebellum
Pons
Responsible for autonomic (involuntary) functions ranging from vomiting to sneezing
Medulla Oblongota
Separates temporal from other landmarks
Lateral Sulcus
Long thin tubular bundle of nervous tissue and support cells
Spinal Chord
Ridge on Cerebral Cortex
Gyrus
Region of frontal cortex directly beneath the frontal bone
Frontal Love
Middle region of the adult brain that develops from the mesencephalon
Midbrain
Deep within the cerebrum, the white matter of this provides the major pathway for communication between the two hemispheres of the cerebral cortex.
Corpus Collosum
cell bodies of neurons with axons that are sensory endings in the periphery, such as in the skin
Dorsal (posterior) root ganglion
receive input from cranial nerves or sacral spinal nerves and are responsible for regulating the parasympathetic aspect of homeostatic mechanisms
Terminal ganglia
Place where axons from different spinal nerves come together
Systemic nerve
