|
||||
show | Belongs to Limbic system. Experiencing and expressing emotion and evaluating an event's emotional significance, such as footsteps. Perform a primary role in the processing and memory of emotional reactions, and considered part of the limbic system.
🗑
|
||||
show | A set of brain structures (thalmus, hippocampus, amygdalae, cingulate gyrus, hypothalmus, fornix, BG, olfactory, septum), that supports emotion, behavior, motivation, long-term memory, and olfaction.
All emotional experience comes from here.
🗑
|
||||
show | Belongs to Limbic system. Plays important roles in consolidation of info from short-to long-term memory and spatial navigation. Located in the medial temporal lobe. One of the first to damage in Alzheimer's. Entry for memories (sights, sounds).

|
||||
Thalamus (Function & Location) | show 🗑

|
||||
show | Belongs to Limbic system. Most important function is to link nervous system to endocrine system via pituitary gland. Located below the thalamus, just above the brain stem. Forms the ventral part of the diencephalon. Regulates metabolic and ANS.
🗑
|
||||
show | Endocrine gland the size of a pea. Not part of the brain but a protrusion off the bottom of the hypothalamus at the base and rests in a small, bony cavity (sella turcica) covered by a dural fold (diaphragma sellae). Secretes nine hormones for homeostasis.
🗑
|
||||
Pineal Gland - (Pineal Body, "Third Eye") | show 🗑
|
||||
show | Located beneath the Sylvian fissure in both hemispheres. Home to primary auditory cortex. Also important for the processing of semantics in both speech and vision. It contains the hippocampus and plays a key role in the formation of long-term memory.
🗑
|
||||
Parietal Lobe (Function) | show 🗑
|
||||
show | The visual processing center of the brain containing most of the anatomical region of the visual cortex. The two lobes are the smallest of four paired lobes in the cerebral cortex.

|
||||
Cerebrum - (Telencephalon) | show 🗑

|
||||
Fissures (Definition) | show 🗑
|
||||
show | Two large blood vessels in your neck that supply the anterior portion of the brain's blood supply.
🗑
|
||||
show | Major arteries of the neck. They branch from the subclavian arteries to form the single midline.
🗑
|
||||
show | A complex from the neck to the brain that merges together to supply blood to the posterior part of the circle of Willis and thus significant portions of the brain.
🗑
|
||||
Basilar Artery (Function & Location) | show 🗑
|
||||
Cerebral Cortex (Function & Location) | show 🗑
|
||||
Interventricular Foramina - (Foramina of Monro) (Function & Location) | show 🗑
|
||||
show | A structure in the ventricles of the brain where CSF is produced. It consists of modified ependymal cells.
🗑
|
||||
Cisterna Magna (Function & Location) | show 🗑
|
||||
Infundibulum - (Pituitary Stalk, "Little Bridge") (Function & Location) | show 🗑
|
||||
show | Believed to be involved in consciousness and diverse functions linked to emotion or regulation homeostasis including: perception, motor control, self-awareness, cognitive, and experience. In relation to these it is involved in psychopathology.
🗑
|
||||
Diencephalon - (Interbrain) (Function) | show 🗑
|
||||
show | A set of connected nuclei in the brain responsible for regulating arousal and sleep-wake transitions. As its name implies, its most influential component is the Reticular formation.

|
||||
