Term
| Autonomic nervous system (ANS) |
|
Definition
| 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. |
|
|
Term
|
Definition
| 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. |
|
|
Term
|
Definition
| A region of the cerebral cortex that is defined by its cytoarchitecture, or histological structure and organization of cells. |
|
|
Term
|
Definition
| A large, highly convoluted (in-folded)structure located dorsal to the brain stem at the level of the pons. Also known as “little cerebrum” |
|
|
Term
|
Definition
| 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, each containing four major lobes. |

Term
|
Definition
| On the opposite side of the body (antonym of ipsilateral). |
|
|
Term
|
Definition
| A plane that shows brain structures as seen from the front. Also called frontal plane. |
|
|
Term
|
Definition
| Located more distant from the point of origin or attachment (antonym of proximal). |
|
|
Term
|
Definition
| 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 (antonym of ventral). |
|
|
Term
|
Definition
| One of the four major lobes of the cerebral cortex. |
|
|
Term
|
Definition
| A major component of the central nervous system that contains primarily neuronal cell bodies. |
|
|
Term
|
Definition
| Below another part (antonym of superior) |
|
|
Term
|
Definition
| On the same side of the body (such as two parts on the left, antonym of contralateral). |
|
|
Term
|
Definition
| Toward the side, away from the midline (antonym of medial). |
|
|
Term
|
Definition
| Toward the midline, away from the side (antonym of lateral). |
|
|
Term
|
Definition
| One of the four major lobes of the cerebral cortex, which holds amongst others the primary visual cortex. |
|
|
Term
|
Definition
| One of the four major lobes of the cerebral cortex, which holds amongst others the primary somatosensory cortex. |
|
|
Term
|
Definition
| Toward the rear end (antonym of anterior). |
|
|
Term
|
Definition
| Located close (approximate) to the point of origin or attachment (antonym of distal). |
|
|
Term
|
Definition
| A plane that shows brain structures as seen from the side. |
|
|
Term
|
Definition
| 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. |
|
|
Term
|
Definition
| Above another part (antonym of inferior). |
|
|
Term
|
Definition
| One of the four major lobes of the cerebral cortex, which holds amongst others the primary auditory cortex. |
|
|
Term
|
Definition
| A group of nuclei, which provide primary sensory relay for somatosensory, gustatory, auditory, visual, and vestibular sensory inputs to the cerebral cortex. |
|
|
Term
|
Definition
| A plane that shows brain structures as seen from above. Also called horizontal plane. |
|
|
Term
|
Definition
| Toward the stomach, away from the dorsal (back) side (antonym of dorsal). |
|
|
Term
|
Definition
| A major component of the central nervous system that contains millions myelinated axons (i.e., the wires between neuronal cell bodies). |
