Paracentral lobule, the Glossary

In neuroanatomy, the paracentral lobule is on the medial surface of the cerebral hemisphere and is the continuation of the precentral and postcentral gyri.^[1]

Anterior cerebral artery

The anterior cerebral artery (ACA) is one of a pair of cerebral arteries that supplies oxygenated blood to most midline portions of the frontal lobes and superior medial parietal lobes of the brain.

Brodmann area

A Brodmann area is a region of the cerebral cortex, in the human or other primate brain, defined by its cytoarchitecture, or histological structure and organization of cells.

Central sulcus

In neuroanatomy, the central sulcus (also central fissure, fissure of Rolando, or Rolandic fissure, after Luigi Rolando) is a sulcus, or groove, in the cerebral cortex in the brains of vertebrates.

Cerebral hemisphere

The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure.

Cingulate sulcus

The cingulate sulcus is a sulcus (brain fold) on the cingulate cortex in the medial wall of the cerebral cortex. Paracentral lobule and cingulate sulcus are medial surface of cerebral hemisphere.

Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system's tissues under the microscope.

Defecation

Defecation (or defaecation) follows digestion, and is a necessary process by which organisms eliminate a solid, semisolid, or liquid waste material known as feces from the digestive tract via the anus or cloaca.

Frontal lobe

The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe).

Marginal sulcus

In neuroanatomy, the marginal sulcus (margin of the cingulate sulcus) is a sulcus (crevice) that may be considered the termination of the cingulate sulcus. Paracentral lobule and marginal sulcus are parietal lobe.

Parietal lobe

The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals.

Postcentral gyrus

In neuroanatomy, the postcentral gyrus is a prominent gyrus in the lateral parietal lobe of the human brain. Paracentral lobule and postcentral gyrus are gyri and parietal lobe.

See Paracentral lobule and Postcentral gyrus

Precentral gyrus

The precentral gyrus is a prominent gyrus on the surface of the posterior frontal lobe of the brain. Paracentral lobule and precentral gyrus are frontal lobe and gyri.

See Paracentral lobule and Precentral gyrus

Precentral sulcus

The precentral sulcus is a part of the human brain that lies parallel to, and in front of, the central sulcus. Paracentral lobule and precentral sulcus are frontal lobe.

Sensory neuron

Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials.
