-
Tuberal Area
- Location: between theInfundibulum of Pituitary gland and the Mamiilary body
- Function: contains nuclei involved with the control of the Pituitary gland fuction
-
ADH
- Name: AntiDiuretic Hormones/Vasopressin
- Location: produced by the Supraoptic Nucleus in the Hypothalamus
- Function: Restrictes water loss at the kidneys
-
OXT
- Name: Oxytocin
- Location: Paraventricular Nucleus in the Hypothalamus
- Function: stimulates smooth muscle contraction of the uterus, mammary glands and the prostate gland.
-
Association fibers
- Purpose: interconnect areas of neural cortex within a single cerebral hemisphere
- Two types:
- Arcuate fibers-pass from one gyrus to another
- Longitudinal Fasciculi-connect Frontal Lobe to other Lobes of the same hemisphere.
-
Commissural fibers
- Purpose: interconnect and allow communication between right and left hemispheres
- (exp) corpus callosum
-
Projection fibers
- Purpose: link the cerebral cortex to the diencephalon, brain stem, cerebellum, and spinal cord.
- Types:
- ascending fibers
- descending fibers
- internal capsule-collection of Projection fibers

- Who: A FNG at Columbia Pool even after almost a year of working
- Why: Who knows.
-
Basal Nuclei
- Name: same as "Basal Ganglia" but term ganglia refers to structures in PNS so not a correct anatomy term
- Function: subconscience control of skeletal muscle tone and the coordination of learned movements.
- Contents:
- Caudate nucleus
- Lentiform nucleus:
- -contains
- -globus pallidus
- -putamen
- Features:
- Corpus striatum(striated body)
-
Ataxia
Disturbance in muscular coordination
-
Circadian Rhythms
24-hour day--night cycle coordinared by the suprachiasmatic nucleus in the hypothalamas
-
Central sulcus
- Purpose:seperates the frontal lobe from the parietal lobes
- pg481
-
Lateral sulcus
- Purpose: serperates the frontal lobe and parietal lobes from the temperal lobe
- pg481
-
Precentral gyrus
- Purpose: contains the primary motor cortex of the brain
- Details: contains Pyramidal cells (Large neurons that have a pyramidal shape) that make specific muscle contract when activated from the somatic motor association area
- pg 484
- im gay
-
Postcentral gyrus
Purpose: contains the primary sensory cortex of the brain (pg 484)
-
Limbic lobe
- Contents: three gyri
- -Cingulate gyrus
- -Parahippocampal gyrus
- -Dentate gyrus
- pg479
-
Amygdaloid body
- Purpose: acts as an interface between the limbic system and the cerebrum and various sensory systems
- also plays a role in:
- -control of the "fight or flight" response
- - regulation of heart beat
- -linking emotions with specific memories
- pg479
-
Hippocampus
- Purpose: important for leaning ,storage and retrival of new long term memories.
- Detail: named in latin "hippocampus" due to structure somewhat reembling a sea horse
- pg 479
-
Eight Functions of the Hypothalamus
- 1. Subconscious control of skeletal muscle contractions
- 2. The control of autonomic functions
- 3.The coordination of activities of the nervous and endocrine systems
- 4. secretion of two hormones(oxt,adh)
- 5.Production of emotions and behavioral drives
- 6.Coordination between voluntary and autonomic functions
- 7. The regulation of body temperture
- 8. The control of circadian rhythms
-
Mammillary body
- Name: mamilla, little breasts
- Purpose:
- process sensory information,including the olfactory sensations pg476
- Contain motor nuclei that control reflex movements associated with wating pg476
-
Somatic sensory association area
Purpose: Monitors activity in the primary sensory cortex
