The subgranular zone (in rat brain). (A) Regions of the dentate gyrus: the hilus, subgranular zone (sgz), granule cell layer (GCL), and molecular layer (ML). Cells were stained for doublecortin (DCX). (B) Closeup of subgranular zone, located between the hilus and GCL, [33] a site of adult neurogenesis. Phenotypes of proliferating cells in the ...
The bases of denticulate ligaments arise in the pia mater and are firmly attached to the arachnoid mater and dura mater at the apex. [2] The denticulate ligaments extend across the subarachnoid space between anterior nerve roots and posterior nerve roots, piercing the intervening spinal arachnoid mater to reach the dura.
Based upon its structure and connectivity, its function is suggested to be related to coordination of different brain functions; i.e. the conductor analogy. Consciousness functionally can be divided into two components: (i) wakefulness, which is arousal and alertness; (ii) content of consciousness, which is the processing of content.
The parietal lobe is located directly behind the central sulcus, superior to the occipital lobe and posterior to the frontal lobe, visually at the top of the back of the head. [18] The make up of the parietal lobe is defined by four anatomical boundaries in the brain, providing a division of all the four lobes. [18]
The eight cerebellar nuclei, located within the deep white matter of each cerebellar hemisphere, are grouped into pairs, with one of each pair in each of the two hemispheres. As a chunk of tissue, the dentate nucleus with overlying cerebellar cortex makes up a functional unit called the cerebrocerebellum. Thus, there is a part of cerebellum ...
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
As the dental pulp is a highly vascularised and innervated region of the tooth, it is the site of origin for most pain-related sensations. [12] The dental pulp nerve is innervated by one of the trigeminal nerves, otherwise known as the fifth cranial nerve. The neurons enter the pulp cavity through the apical foramen and branch off to form the ...
Vessels and nerves: :25. dental :26. periodontal :27. alveolar through channel. In dental anatomy, the apical foramen, literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's ...
