What is a Cinereum?
What is a Cinereum?
: an eminence of gray matter which lies on the lower surface of the brain between the optic tracts and in front of the mammillary bodies and of which the upper surface forms part of the floor of the third ventricle and the lower surface bears the infundibulum to which the pituitary gland is attached.
Where is the tuber cinereum located?
hypothalamus
The tuber cinereum is located in the hypothalamus. The tuber cinereum is situated above the optic chiasm, where the optic nerves intersect. It is directly below the mammillary bodies, which help regulate memory.
Where is the pituitary stalk?
The pituitary stalk, known as the infundibulum or infundibular stalk, is the connection between the hypothalamus and the pituitary gland, especially the posterior pituitary gland.
What is Infundibular recess?
Medical Definition of infundibular recess : a funnel-shaped downward prolongation of the floor of the third ventricle of the brain behind the optic chiasma into the infundibulum of the pineal gland.
Which nucleus lies deep to the tuber cinereum?
arcuate nucleus
The tuber cinereum is a hollow eminence of the middle–ventral hypothalamus, specifically the arcuate nucleus, situated between the mammillary bodies and the optic chiasm….

What is the hypophyseal stalk?
The pituitary stalk (also known as the infundibular stalk, Fenderson’s funnel, or simply the infundibulum) is the connection between the hypothalamus and the posterior pituitary.

What part of the brain controls appetite and sleep patterns?
The hypothalamus controls your pulse, thirst, appetite, sleep patterns, and other processes in your body that happen automatically. The hypothalamus also controls the pituitary gland, which makes the hormones that control growth, metabolism, water and mineral balance, sexual maturity, and response to stress.
What is Rathke’s pocket?
Rathke’s pouch is a diverticulum arising from the embryonic buccal cavity, from which the anterior pituitary gland develops. Craniopharyngiomas are composed of well-differentiated epithelial elements, including cysts and ameloblasts, and bone.
What does the preoptic area do?
The preoptic area of the hypothalamus (POA) serves as an essential brain region to coordinate sleep and body temperature. Understanding how these two behaviors are controlled within the POA requires the molecular identification of the involved circuits and mapping their local and brain-wide connectivity.
What tells your brain that you are full?
Your stomach tells your brain that it is full. Normally, this feeling causes you to stop eating and not think about food again for several hours. Fullness is partly controlled by the hypothalamus, your blood sugar, and having food in your stomach and intestines.
