|
Term
|
Definition
Location: medial temporal lobe of the brain
Function: limbic system, consolidation of information from short term to long term memory |
|
|

|
|
Term
|
Definition
Location: thin, triangular, vertical membrane separating the anterior horns of the left and right lateral ventricles of the brain
Fuction: pleasure center |
|
|
Term
|
Definition
| Afferent sensory root of a spinal nerve |
|
|
Term
|
Definition
| efferent (motor) root of a spinal nerve |
|
|
Term
|
Definition
| a nodule on a dorsal root that contains cell bodies of neurons in afferent spinal nerves. |
|
|
Term
|
Definition
| the ganglia of the sympathetic nervous system. They deliver information to the body about stress and impending danger, and are responsible for the familiar fight-or-flight response. |
|
|
Term
|
Definition
| the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord. The central canal is continuous with the ventricular system of the brain. |
|
|
Term
|
Definition
set of brain structures, including
hippocampus
amygdalae
anterior thalamic nuclei, septum
limbic cortex
fornix
support a variety of functions including emotion, behavior, motivation, long-term memory, and olfaction. |
|
|
Term
|
Definition
a group of nuclei of varied origin in the brains of vertebrates that act as a cohesive functional unit.
Location: situated at the base of the forebrain and are strongly connected with the cerebral cortex, thalamus and other brain areas
Function: voluntary motor control, procedural learning relating to routine behaviors or "habits" such as bruxism, eye movements, and cognitive, emotional functions |
|
|
Term
|
Definition
| structure of the vertebrate forebrain involved in olfaction, the perception of odors. |

|
|
Term
|
Definition
| a broad term defined as any area in the nervous system composed of mostly unmyelinated axons, dendrites and glial cell processes that forms a synaptically dense region containing a relatively low number of cell bodies. The most prevalent anatomical region of neuropil is the brain which, although not completely composed of neuropil, does have the largest and highest synaptically-concentrated areas of neuropil in the body. |
