Medulla Anatomy

The medulla oblongata is a portion of the hindbrain that controls autonomic functions such as breathing digestion heart and blood vessel function swallowing and sneezing. Medulla oblongata is the transition from the spinal cord to the brain it ends at the foramen magnum or the uppermost rootlets of the first cervical nerve and to which cranial nerves vi to xii are attached.

The Medulla Oblongata Internal Structure Vasculature

The medulla oblongata or medulla is a long stem like structure which makes up part of the brainstem.

Medulla anatomy. Gross anatomy gross structure. Medulla oblongata gross anatomy. Somewhat striated inner section the medulla containing the loops of henle and the collecting tubules.

It is anterior and partially inferior to the cerebellum. Medulla anatomy with mri this photo gallery presents the anatomy of medulla by means of mri t1 weighted sagittal axial and coronal views. As the ureter enters the kidney it enlarges into a cavity the renal pelvis.

It is a cone shaped neuronal mass responsible for autonomic involuntary functions ranging from vomiting to sneezing. There are several main venous drainage routes for the medulla. Level of decussation of the pyramids.

The vertebrobasilar system is responsible for supplying the medulla oblongata. The caudal border of the medulla is the 1 st cervical spinal nerves. Similar to the spinal cord the fourth ventricle is surrounded by white matter on the outside with the gray matter on the inside.

The myelencephalon portion of the rhombencephalon or hindbrain becomes the medulla. The upper portion of the dorsal medulla forms the lower region of the fourth ventricle a fluid filled cavity formed by the expansion of the central canal of the spinal cord upon entering the brain. The medulla oblongata is a funnel shaped structure that constitutes.

Level of decussation of the medial lemnisci. Urine passes into this pelvis from the collecting tubules. Nephrons are numerous 20000 in a mouse.

Medulla oblongata contains the vital autonomic cardiovascular and respiratory centers controlling heart rate blood pressure and breathing. It is not possible to live without medulla as it performs a plethora of crucial tasks like breathing speaking eating blood pressure and more. Motor and sensory neurons from the midbrain and forebrain travel through the medulla.

Level of the olives. The medulla oblongata is an integral part of the brain that manages and controls various voluntary and involuntary functions of the brain. Three levels of the medulla are typically discussed inferior superior.

The medulla is approximately 3 cm in length and 2 cm in greatest diameter 2.
