Central Nervous System (CNS) |
The part of the vertebrate nervous system that is located WITHIN the skull and spine. |
|
Peripheral Nervous System (PNS) |
The part of the vertebrate nervous system that is located OUTSIDE the skull and spine.
|
|
Cervical Region
|
The section of the spine that provides the flexible framework of the neck or cervix; it lies between the skull and the thoracic region. |
|
Thoracic Region |
The section of the spine to which the ribs are attached;it lies between the cervical and the lumbar regions. |
|
Lumbar Region |
The section of the spine that supports the small of the back; it lies between the thoracic region and the sacral region. |
|
Sacral Region |
The section of the spine to which the bones of the pelvis ate attached; it lies adjacent to the lumbar region
|
|
Brain |
The part of the central nervous system that is located in the skull
|
|
Spinal Cord |
The part of the central nervous system that is located in the spine |
|
Somatic Nervous System |
The division of the peripheral nervous system that interacts with the external environment; t conducts sensory signals to the CNS from external receptors and receptors in joints and skeletal muscles, and it conducts motor signals from the CNS to skeletal muscles |
|
Autonomic Nervous System
|
The division of the peripheral nervous system that participates n the regulation of the body's internal environment; it conducts sensory signals to the CNS from receptions in internal organs, and motor signals from the CNS back to the same internal organs |
|
horizontal sections |
slices of the brain that are cut in a horizontal plane, that is, cut parallel to the horizon when the subject is in an upright position
|
|
Sagittal sections
|
slices that are cut parallel to the vertical plane that divides the brain into left and right halves |
|
midsagittal section |
a sagittal cut that is cut from the very midline of the brain |
|
coronal sections |
cut approximately parallel to the surface of the face |
|
cross sections |
sections that are cut at right angles to the long axis of any long narrow structure, for example, at right angles to the long axis of the spinal cord. |
|
anterior |
toward the nose end; aka rostral |
|
posterior |
toward the tail end; aka caudal
|
|
dorsal |
toward the surface of the back or top of the head |
|
ventral |
toward the surface of the chest and stomach or bottom of the head |
|
medial |
toward the midsagittal plane |
|
lateral |
away from the midsaggital plane; toward the left and right |
|
superior |
toward the dorsal surface of the primate head |
|
inferior |
toward the ventral surface of the primate head |
|
unilateral |
on one side of the body |
|
bilateral |
on both sides of the body |
|
ipsilateral |
from or to the same side of the body |
|
contralateral |
from or to the opposite side of the body
|
|
cerebral hemisphere |
the two large neural structures that sit atop the vertebrate brain stem, one on the left and one on the right; they mediate complex psychological processes |
|
Brain stem |
the central neural stem on which the two cerebral hemispheres sit; many brain stem structures play key roles in the regulation of the body's inner environment |
|
Telencephalon |
the cerebral hemispheres; one of the two divisions of the forebrain (the other one is the diencephalon)
|
|
Diencephalon |
the region of the brain between the telencephalon and the mesencephalon; one of the two divisions of the forebrain (the other is the telencephalon); the most anterior region of the brain stem
|
|
Mesencephalon |
the midbrain; the region of the brain stem between the deincephalon and the metencephalon |
|
Metencephalon |
the region of the brain stem between the mesencephalon and the spinal cord; one of the two divisions of the hindbrain (the other is the metencephalon) |
|
Dura mater |
the outermost and toughest of the three meninges
|
|
Arachnoid membrane |
the middle menynx' it has the texture of a gauze like spider web.
|
|
Pia Mater |
the innermost and most delicate of the three meninges; it adheres to the surface of the CNS
|
|
Subarachnoid Space |
the space between the main part of the arachnoid membrane and the pia mater; it contain cerebrospinal fluid, the web-like processes of the arachnoid layeer and many blood vessels |
|
Cerebrospinal fluid |
the fluid that fills both the subarachnoid space and the hollow core of the brain and spinal cord, it supports, nourishes and cushions the central nervous system |
|
Central Canal |
the cerebrospinal-fluid-filled internal space that runs the length of the spinal cord |
|
lateral ventricles |
the ventricles of the left and right cerebral hemispheres; they are the largest of the four cerebral ventricles |
|
third ventricle |
the cerebral ventricle of the diencephalon; it is a ventrical sheet-shaped chamber that lies along the midline. |
|
Fourth Ventricle |
the cerebral ventricle of the metencephalon; it connects the cerebral aqueduct and the central canal |
|
Cerebral aqueduct |
the narrow channel that connects the third and fourth venticles; most of it is located in the mesencephalon |
