Brainstem: Its Function and Location 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. Most cranial nerves are also located in the brainstem.

Brainstem The medulla oblongata often just referred to as the medulla, is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. The medulla contains the cardiac, respiratory, vomiting and vasomotor centres dealing with heart rate, breathing and blood pressure.hough small, this is an extremely important part of the brain as the nerve connections of the motor and sensory systems from the main part of the brain to the rest of the body pass through the brainstem.

Brainstem The brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord. In the human brain the brainstem includes the midbrain, the pons, and the medulla oblongata. Sometimes the diencephalon, the caudal part of the forebrain, is included.[1]

cerebellum (sĕr′ə-bĕl′əm) The part of the vertebrate brain that is located below the cerebrum at the rear of the skull and coordinates balance and muscle activity. In humans and other mammals, the cerebellum is made up of two connecting parts, called hemispheres, consisting of a core of white matter surrounded by gray matter.

Brainstem (January 2013). In the anatomy of humans and of many other vertebrates, the brainstem (or brain stem) is the posterior part of the brain, adjoining and structurally continuous with the spinal cord.here are three main functions of the brainstem: 1  The brainstem plays a role in conduction. 2  The cranial nerves III-XII emerge from the brainstem. 3  The brainstem has integrative functions being involved in cardiovascular system control, respiratory control, pain sensitivity control, alertness, awareness, and consciousness.

Brain The pons and medulla, also located within the brainstem, are the respiratory centers. The cerebrum, the largest part of the brain, controls thought processes and memory. The cerebellum, located inferoposterior to the cerebrum, regulates coordination, balance, and equilibrium. ... The reticular activating system (RAS), which is located within the brainstem, controls a person's state of awareness and level of consciousness.

Brainstem Brainstem, area at the base of the brain that lies between the deep structures of the cerebral hemispheres and the cervical spinal cord. The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon). 1  The brainstem houses many of the control centres for vital body functions, such as swallowing, breathing, and vasomotor control.

Human brain The pons and the medulla, two major elements of the brainstem, channel nerve signals between the brain and other parts of the body, controlling vital functions such as breathing and deliberate movement.he preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain's total volume) is actually a recent development in the course of evolution.

- The Human Brain. The human brain is a unique and complex structure; it facilitates vital and complicated physiological and psychological functions such as consciousness, mobility, emotion, and personality. Different parts of the brain are responsible for specific functions.he brainstem is connected to the spinal cord at the back of the brain. The brainstem controls unconscious functions such as respiration, digestion, and pulse. Three structures comprise the brainstem: the midbrain, the pons, and the medulla oblongata. The midbrain controls eye movement and focus.

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.

The Brain Stem The brainstem regulates vital body functions such as cardiac and respiratory functions and acts as a vehicle for sensory information. Describe the functions of the brainstem. In vertebrate anatomy, the brainstem (or brain stem) is the posterior part of the brain adjoining, and structurally continuous with, the spinal cord.
