Adrenal Gland
...  gland is a small triangular gland located on top of the kidney. Adrenal glands are orange-coloured endocrine glands that are about one-half inch tall and three inches wide. The gland consists of a medulla and is surrounded by the cortex. It is responsible for producing epinephrine and norepinephrine, as well as the hormones related with stress through the process of corticosteroids. One of  ...

Parasympathetic Division
...  abdomen or in the head. Preganglionic neurons are produced in the spinal column and the brain. Majority of the neurons in the parasympathetic division originate from the midbrain, the pons and the medulla oblongata. The effects of the action of the parasympathetic division are opposite to that of sympathetic, and the process is “rest and digest” instead of “fight or  ...

Abducens Nerve
...  nerve? There are two abducens nerves in the body, one for each eye. This pair is the sixth of the cranial nerves and it is composed of motor fibers. It leaves the brainstem at the junction of the medulla and pons. It is located medial to the facial nerve. For it to reach the eye, it runs upward and then bends forward. How does the nerve work? After emerging from the brainstem, the nerve  ...

Blood Supply to the Brain
...  neck. For the blood supply to enter the brain, these arteries pass through the foramen magnum. This is an opening at the base of the skull where the spinal cord merges with the brain region of the medulla oblongata. The arteries are conjoined once they have penetrated the cranium to form the basilar artery. This artery, in turn, serves as the seed where two posterior cerebral arteries are  ...

Medulla Oblongata
...  medulla oblongata is the undermost portion in the stem of the brain, and is measuring approximately 3 centimeters long. Its structure is bulbous, and it is attached anteriorly in the pons. It is also connected posteriorly in the spinal cord. medulla oblongata is situated at the same level as with foramen magnum. When it is viewed externally, it would look similar to the spinal cord except for  ...

Mesencephalon
...  together with its corresponding tracts is located within the system of the brain. This section of the brain is vital, because it is attached to the spinal cord. The midbrain, the pons and the medulla oblongata are also found there. What is Inside the Mesencephalon? The mesencephalon, or the midbrain has these parts inside it: corpora quadrigemina, red nucleus, the cerebral peduncles and  ...

Pons
...  metencephalon then controls the skeletal muscle contraction. The distinct characteristic of the pons is its circular bulge which lies on the brain’s inferior side. It could be seen between the medulla oblongata and the midbrain. It is created in through tracts of white colored fiber in two principle directions. One, it transversely extends throughout the middle part of cerebellar  ...

Spinal Cord
...  spinal cord is a part of the central nervous system characterized by a long and thin bundle of tissues and cells that extends to the medulla. This and the brain make up the CNS, or the central nervous system. Its length is extended to the space of the first and second lumbar vertebrae, but does not extend until the vertebral column. It is made up primarily of gray matter and is located in the  ...
