Medulla oblongata Medulla oblongata. The medulla oblongata is located in the brain stem, anterior to (in front of) the cerebellum. This is a cone-shaped, neuronal (nerve cell) mass in the hindbrain, which controls a number of autonomic (involuntary) functions.

What does the medulla oblongata do? The medulla oblongata is the part of the brain that controls autonomic functions. Some of the functions that it controls are digestion, breathing, heart function, and swallowing.he medulla oblongata, commonly known as simply the medulla, is the lower half of the brain stem. It controls the cardiac, respiratory systems and other autonomic systems.

Parts of the Brain Stem: The Medulla Oblongata and Pons A tiny little area in your brain is what gives you the ability to breathe and enjoy life. These little areas are located in two important areas of your brain stem, known as the pons and medulla oblongata. We'll also learn about their structure and function, including chemoreceptors, pH sensing, and breathing rate.

Pyramid Pyramid. Two pyramid-shaped swellings are located on the medulla oblongata, on either side of its ventral (front) midline.More commonly referred to together as the brain stem, the pyramids are specifically located between the anterolateral sulcus and the anterior median fissure of the medulla.The pyramids appear as two ridges that travel down the entire length of the medulla.t the medulla's back-most point, directly above the beginning of the cervical spinal cord, the fibers of each pyramid cross in a process referred to as the decussation of the pyramids.

Pons Pons. The pons is a portion of the brain stem, located above the medulla oblongata and below the midbrain. Although it is small, at approximately 2.5 centimeters long, it serves several important functions.

What is the Medulla? - Definition, Function & Location The medulla oblongata, also known just as the medulla, is part of your brainstem, which is literally the stem that extends from your brain. The medulla sits below the pons and above the spinal cord and is a major relay point for information going to and from your brain and spinal cord.

Medulla oblongata The medulla can be thought of as being in two parts: an upper open part or superior part where the dorsal surface of the medulla is formed by the fourth ventricle. a lower closed part or inferior part where the fourth ventricle has narrowed at the obex in the caudal medulla, and surrounds part of the central canal. External surfaces. The anterior median fissure contains a fold of pia mater, and extends along the length of the medulla oblongata.

Human brain The brainstem consists of the midbrain, medulla oblongata, and the pons. Credit: SEER Training Modules/ U. S. National Institutes of Health, National Cancer Institute. Brainstem: The brainstem is the region of the brain that connects the cerebrum with the spinal cord. It consists of the midbrain, medulla oblongata, and the pons. Motor and sensory neurons travel through the brainstem allowing for the relay of signals between the brain and the spinal cord. The brainstem coordinates motor control signals sent from the brain to the body.

Medulla oblongata The medulla oblongata is located in the brainstem, anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic functions ranging from vomiting to sneezing. The medulla contains the cardiac, respiratory, vomiting and vasomotor centers and therefore deals with the autonomic functions of breathing, heart rate and blood pressure. The bulb is an archaic term for the medulla oblongata and in modern clinical usage the word bulbar is retained for terms

Medulla oblongata Written By: Medulla oblongata, also called medulla, the lowest part of the brain and the lowest portion of the brainstem. The medulla oblongata is connected by the pons to the midbrain and is continuous posteriorly with the spinal cord, with which it merges at the opening (foramen magnum) at the base of the skull.

Encyclopedia index The medulla oblongata, also called the myelencephalon, is the lowest part of the brainstem. The medulla oblongata looks like a swelling at the tip of the spinal cord; it is continuous with the spinal cord above the level of the foramen magnum of the occipital bone. From the level of the foramen magnum it proceeds almost vertically upward to end at the lower border of the pons.

- In the lumbar regions, the cone-shaped terminus of the spinal cord (conus medullaris) normally ends at about the L1 or L2 level in adults. Caudal to these levels, the roots of the cauda equina are contained within the subarachnoid space of the dura-enclosed thecal sac (Figure 3).

What is the conus medullaris? Sections. Conus medullaris is the cone-shaped end of the spinal cord. It is normally located between the end of the thoracic vertebrae (T12) and the beginning of the lumbar vertebrae (L1), though sometimes the conus medullaris is found between L1 and L2.ections.

Since this structure is part of the spinal cord but is in close proximity to spinal nerve roots, lesions often produce both upper motor neuron and lower motor neuron deficits.

Introduction to Psychology âPSY101 WHAT IS PSYCHOLOGY? Your two adrenal glands are small, triangular-shaped endocrine glands located on the top of each kidney. Each adrenal gland is approximately 3 inches wide, and a half inch high. Each gland is divided into an outer cortex and an inner medulla. The cortex and medulla of the adrenal gland secrete different hormones. The adrenal cortex is essential to life, but the medulla may be removed with no life-threatening effects.
