The part of the PNS that influences the function of internal organs. The ANS acts largely unconsciously and regulates the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
2 of 28
brainstem
The posterior part of the brain, adjoining and structurally continuous with the spinal cord. In humans, it is usually described as including the medulla oblongata, pons, and midbrain.
3 of 28
brodmann area
A region of the cerebral cortex that is defined by its cytoarchitecture, or histological structure and organization of cells.
4 of 28
cerebellum
A large, highly convoluted (in-folded) structure located dorsal to the brainstem at the level of the pons
5 of 28
cerebral cortex
The layered sheet of neurons that covers the surface of the brain and contains the machinery for creating perception, as well other functions, such as language, memory, and thinking. It is divided in two (lateral) hemispheres, contains 4 major lobes
6 of 28
contralateral
on the opposite side of the body
7 of 28
coronal plane
A plane that shows brain structures as seen from the front. Also called frontal plane
8 of 28
distal
located more distant from the point of origin or attachment
9 of 28
dorsal
Toward the back, away from the ventral (stomach) side. The top of the brain is considered dorsal because it has this position in four-legged animals
10 of 28
frontal lobe
one of four major lobes of cerebral cortex
11 of 28
gray matter
A major component of the central nervous system that contains primarily neuronal cell bodies.

inferior
below another part
13 of 28
ipsilateral
On the same side of the body
14 of 28
lateral
toward the side, away from midline
15 of 28
medial
toward midline, away from side
16 of 28
occipital lobe
One of the four major lobes of the cerebral cortex, which holds amongst others the primary visual cortex.
17 of 28
parietal lobe
One of the four major lobes of the cerebral cortex, which holds amongst others the primary somatosensory cortex
18 of 28
posterior
towards the rear end
19 of 28
proximal
located close to point of origin or attachment
20 of 28
sagittal plane
a plane that shows brain structures as seen from the side
21 of 28
somatic nervous system
The part of the PNS that is associated with body movements through the control of skeletal (voluntary) muscles and with the reception of external stimuli.
22 of 28
superior
above another part
23 of 28
temporal lobe
One of the four major lobes of the cerebral cortex, which holds amongst others the primary auditory cortex
24 of 28
thalamus
A group of nuclei, which provide primary sensory relay for somatosensory, gustatory, auditory, visual, and vestibular sensory inputs to the cerebral cortex.
25 of 28
transverse plane
A plane that shows brain structures as seen from above. Also called horizontal plane
26 of 28
ventral
towards the stomach, away from the dorsal side
27 of 28
white matter
A major component of the central nervous system that contains millions myelinated axons (i.e., the wires between neuronal cell bodies).
