Medulla

It can be hard to distinguish between the cortex and medulla, but follicles are usually not found in the medulla.

Medulla main The adrenal medulla is at the centre of each adrenal gland, and is surrounded by the adrenal cortex.

The chromaffin cells of the medulla are the body's main source of the catecholamines adrenaline and noradrenaline, released by the medulla.

Then the bullfighter's assistant slices the medulla oblongata to slowly halt respiratory and cardiac functions.

Although the inferior olive lies in the medulla oblongata and receives input from the spinal cord, brainstem and cerebral cortex, its output goes entirely to the cerebellum.

At about the same time, the hindbrain splits into the metencephalon (which will contain the cerebellum and pons) and the myelencephalon (which will contain the medulla oblongata ).

Because of this anatomy, injuries to the pyramidal tract above the medulla generally cause contralateral hemiparesis (weakness on the opposite side as the injury).

By binding to ganglion type nicotinic receptors in the adrenal medulla, nicotine increases flow of adrenaline (epinephrine), a stimulating hormone and neurotransmitter.

Distinctive features of the mammalian kidney, in comparison with that of other vertebrates, include the presence of the renal pelvis and renal pyramids, and of a clearly distinguishable cortex and medulla.

In a manuscript written between 1741 and 1744, unpublished in his lifetime, Swedenborg referred to CSF as "spirituous lymph" secreted from the roof of the fourth ventricle down to the medulla oblongata and spinal cord.

Information from these sets of sensors is sent to the respiratory center in the medulla oblongata of the brain which activates the effector organs, which, in this case, are the skeletal muscles of respiration (particularly the diaphragm ).

Injuries at the lower medulla, spinal cord, and peripheral nerves result in ipsilateral hemiparesis.

It consists of two olfactory lobes, two cerebral hemispheres, a pineal body, two optic lobes, a cerebellum and a medulla oblongata.

Splanchnic nerves of the sympathetic nervous system innervate the medulla of the adrenal gland.

The central adrenomedullary vein, in the adrenal medulla, is an unusual type of blood vessel.

The cerebellum is the center of muscular coordination and the medulla oblongata controls some organ functions including heartbeat and respiration.

The guard hairs of the Eurasian beaver have a longer hollow medulla at their tips.

The medulla is specialised to allow thymocytes to undergo additional rounds of negative selection to remove auto-reactive T-cells from the mature repertoire.
