What is the elevated ridge of cerebral tissue?

18
A(n) gyrus is an elevated ridge of cerebraltissue. The convolutions seen in the cerebrum are important becausethey increase the surface area. Gray matter is composed of neuroncell bodies.


Also, what is an elevated ridge of cerebral cortex tissue?

Elevated ridges of tissue, called gyri(singular: gyrus), separated by shallow groves called sulci(singular: sulcus) mark nearly the entire surface of thecerebral hemispheres.

Similarly, why trauma to the base of the brain is more dangerous? EXPLAIN WHY TRAUMA TO THE BASE OF THE BRAIN ISOFTEN MUCH MORE DANGEROUS THEN TRAUMA TO THE FRONTALLOBE. THE BASE OF THE BRAIN IS MORE DANGEROUS THENTRAUMA TO FRONTAL LOBES BECAUSE IT CONTAINS THE CENTERSMORE VITAL TO LIFE SUCH AS, RESPIRATORY, CARDIAC, ANDVASOMOTOR CENTERS.

Subsequently, question is, what is the most important autonomic center of brain?

The medulla oblongata (myelencephalon) is the lower halfof the brainstem continuous with the spinal cord. Its upper part iscontinuous with the pons. The medulla contains the cardiac,respiratory, vomiting, and vasomotor centers regulatingheart rate, breathing, and blood pressure.

What are the cavities found in the brain called?

Ventricles and cerebrospinal fluid The brain has hollow fluid-filled cavitiescalled ventricles (Fig. 7).

What is the center ridge of the brain called?

The surface of the brain is folded intoridges (gyri) and grooves (sulci), many of which arenamed, usually according to their position, such as thefrontal gyrus of the frontal lobe or the central sulcusseparating the central regions of thehemispheres.

What lobe of the cerebral cortex controls the sense of sight?

The frontal lobe is important for cognitivefunctions and control of voluntary movement or activity. Theparietal lobe processes information about temperature,taste, touch and movement, while the occipital lobe isprimarily responsible for vision.

What is the outermost covering of the brain?

In between the skull and brain are three layersof tissue, called meninges. They protect the brain.The strong, outermost layer is named the dura mater. Themiddle layer, the arachnoid mater, is a thin membrane made of bloodvessels and elastic tissue.

Where are cerebral Peduncles located?

The cerebral peduncles are located oneither side of the midbrain and are the frontmost part of themidbrain, and act as the connectors between the rest of themidbrain and the thalamic nuclei and thus thecerebrum.

Which of the following structures provides for communication between the two hemispheres of the brain?

The two hemispheres communicate with one anotherthrough the corpus callosum. The corpus callosum is a wide, flatbundle of neural fibers beneath the cortex that connects the leftand right cerebral hemispheres and facilitatesinterhemispheric communication.

What structure is a major relay and processing station for all information passing to the cerebral cortex answer?

The brainstem is the lower extension of thebrain, located in front of the cerebellum andconnected to the spinal cord. It consists of threestructures: the midbrain, pons and medulla oblongata. Itserves as a relay station, passing messages back andforth between various parts of the body and the cerebralcortex.

What coordinates are complex muscle movements?

The cerebellum receives information from the sensorysystems, the spinal cord, and other parts of the brain and thenregulates motor movements. The cerebellum coordinatesvoluntary movements such as posture, balance, coordination,and speech, resulting in smooth and balanced muscularactivity.

What is gray matter in the brain?

Function. Grey matter contains most of thebrain's neuronal cell bodies. The grey matterincludes regions of the brain involved in muscle control,and sensory perception such as seeing and hearing, memory,emotions, speech, decision making, and self-control. The anteriorgrey column contains motor neurons.
