What does the hypothalamus extend from and to
Optic chiasm to the caudal border of the mamillar border
What is the hypothalamus apart of
Diencephalon
Where does the hypothalamus lie
Below the thalamus
Explain the anatomical structure boundaries of the Hypothalamus :
-Superior
-Inferolateral
-Anterior
-Posterior
-Lateral
-Superior: Thalamus
-Inferolateral: Subthalamic region
Anterior- Preptic area
-Posterior - tegmentum of the midbrain
In the hypothalamus name the structures visibke from below the brain
- Optic chiasma
-Tuber cinereum + infundibulum
-Mamillary bodies
What is the 2 functions/roles of the hypothalamus
- Integrative role
-Vital for homeostasis
Explain the integrative role of the hypothalamus- function
- Regulates ANS and Endocrine system
Explain the vital for homeostasis function of the hypothalamus- what it controls
-Regulates:
-Body temperature
-Body fluids
-Hunger and thirst
-Sexual behaviour
-Emotions
What is the hypothalamic nuclei composed of
Small nerve cells grouped into nuclei
In the hypothalamic nuclei, what do many nuclei lack
Lack clear boundaries
What is the hypothalamic nuclei divided by and into what
- Divided by :
-An imganinary parasagittal plane into - Medial zone
-Lateral zone
Name the 8 nuclei the Medial zoneof the hypothalmic nuclei contains
- Preoptic nucleus
-Anterior nucleus
-Suprachiasmatic nucleus
-Paraventricular nucleus
-Dorsomedial
Ventromedial
-Infundibular
-Posterior nucleus
Name the 6 nucleus the lateral zone of the hypothalamus contains
- Preoptic nucleus
-Suprachiasmatic nucleus
-Suproptic nucleus
-Lateral nucleus
-Tuberomamillary nucleus
-Lateral tuberal nuclei
What is the overlapping zone of the hypothalamus
The span of both zones
Name the 3 nuclei that the overlapping zone of the hypothalamic nuclei contains
- Preoptic nucleus
