The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain’s primary somatic sensory cortex (see image 2), a region where the brain interprets input from other areas of the body.
What is the best definition of parietal lobe?
parietal lobe. noun. the portion of each cerebral hemisphere concerned with the perception and interpretation of sensations of touch, temperature, and taste and with muscular movements.
What is the function of the parietal lobe in the brain?
The parietal lobe is behind the frontal lobe, separated by the central sulcus. Areas in the parietal lobe are responsible for integrating sensory information, including touch, temperature, pressure and pain.
What is an example of parietal?
For examples, there are the: Parietal bone — the main side bone of the skull. Parietal lobe — the main side lobe of the brain (it is beneath the parietal bone). Parietal pericardium — the outer membrane around the heart.
What is parietal lobe in psychology? – Related Questions
What are the two main functions of the parietal lobe?
The parietal lobe is located just under the parietal bone of the skull. This important brain lobe helps integrate sensory input and process language.
What happens when you damage your parietal lobe?
Parietal Lobe, Right – Damage to this area can cause visuo-spatial deficits (e.g., the patient may have difficulty finding their way around new, or even familiar, places). Parietal Lobe, Left – Damage to this area may disrupt a person’s ability to understand spoken and/or written language.
What do you mean by parietal?
adjective. 1. anatomy, biology. of, relating to, or forming the walls or part of the walls of a bodily cavity or similar structure. the parietal bones of the skull.
What are the two parietal bones?
The parietal bones (/pəˈraɪ. ɪtəl/) are two bones in the skull which, when joined at a fibrous joint, form the sides and roof of the cranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles.
What is a parietal in biology?
parietal cell, also called Oxyntic Cell, or Delomorphous Cell, in biology, one of the cells that are the source of the hydrochloric acid and most of the water in the stomach juices.
How do you use parietal in a sentence?
At age 71 I had a meningioma in the left parietal. Thus, high acid production by the parietal cells probably protects the corpus mucosa from initial colonization. These areas appear to be the temporal or parietal neocortex.
What is another word for parietal lobe?

What are the 4 major areas of the parietal lobe?
The following are some key areas of the parietal lobe:
- Somatosensory cortex. The somatosensory cortex in the front part of the parietal lobe resides in two areas: the postcentral gyrus and the posterior paracentral lobule.
- Superior parietal lobule.
- Super marginal gyrus.
- Angular gyrus.
What is the other name of parietal?
Parietal cells (also known as oxyntic cells) are epithelial cells in the stomach that secrete hydrochloric acid (HCl) and intrinsic factor. These cells are located in the gastric glands found in the lining of the fundus and body regions of the stomach.
Where is the parietal lobe located?
Where is the Parietal Lobe Located? The parietal lobe of the brain is situated between the frontal and occipital lobes, and above the temporal lobes. The parietal lobes take up premises in both the right and left hemispheres of the brain.
Is the parietal lobe involved in language?
The left parietal lobe has been proposed as a major language area. However, parietal cortical function is more usually considered in terms of the control of actions, contributing both to attention and cross-modal integration of external and reafferent sensory cues.
What are parietal cells stimulated by?
Parietal cells are stimulated directly and indirectly by neural (acetylcholine), endocrine (gastrin), and paracrine (histamine) mechanisms.
What supplies the parietal lobe?
The middle cerebral artery supplies large portions of the frontal, parietal, and temporal lobe surfaces. Branches of the anterior and middle cerebral arteries (lenticulostriate arteries) supply the basal ganglia and anterior limb of the internal capsule.
What happens when parietal cells are activated?
When stimulated, parietal cells secrete HCl at a concentration of roughly 160 mM (equivalent to a pH of 0.8). The acid is secreted into large cannaliculi, deep invaginations of the plasma membrane which are continuous with the lumen of the stomach.
Why is parietal cells important?
[1][2] Parietal cells play a pivotal role in gastric homeostasis, as well as in the absorption of vitamin B12 (cobalamin) due to the release of intrinsic factor (IF). [3] Paracrine, endocrine, and neural pathways are involved in the rigorous control of acid secretion by parietal cells.
Why is it called parietal?
The name comes from the parietal bone, which is named from the Latin paries-, meaning “wall”.
