What is a Cortical Neuron? Cortical neurons are the cells of the brain's largest region, the two hemispheres of the cerebral cortex. Most of the complex activity of the brain enabling thought, perception, and voluntary movement is connected to the activity of these neurons.

- The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries. It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons.

Cortical homunculus A 2-D cortical sensory homunculus. A cortical homunculus is a distorted representation of the human body, based on a neurological map of the areas and proportions of the brain dedicated to processing motor functions, or sensory functions, for different parts of the body.

Organ of Corti (December 2014). The organ of Corti, or spiral organ, is the receptor organ for hearing and is located in the mammalian cochlea. Described as a masterpiece of cellular micro-architecture, this highly varied strip of epithelial cells allows for transduction of auditory signals into nerve impulses' action potential.he function of the organ of Corti is to transduce auditory signals and maximize the hair cells’ extraction of sound energy. It is the auricle and middle ear that act as mechanical transformers and amplifiers so that the sound waves end up with amplitudes 22 times greater than when they entered the ear.

AGC A microfold cell, which is a cell in the gastrointestinal epithelium covering patches of lymphoid tissue. M cells transport antigens from the intestinal lumen to the underlying lymphoid tissues for recognition and processing. cell whose function is to reproduce the organism. Early in development, primordial germ cells are found in the genital ridges of the embryo. Later, in the testis, the primordial germ cells are called spermatogonia, and in the ovary, they are called oogonia.

- The juxtaglomerular apparatus is a collective term referring to the cells near a structure called the glomerulus in the kidney. The juxtaglomerular cells are specialized cells that stimulate the secretion of the adrenal hormone aldosterone and play a major role in renal autoregulation, the kidney's self-governance.

Cone cell Cone cells, or cones, are one of two types of photoreceptor cells in the retina of the eye. They are responsible for color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light.one cells are densely packed in the fovea centralis, a 0.3 mm diameter rod-free area with very thin, densely packed cones which quickly reduce in number towards the periphery of the retina.

Cerebral cortex The cerebral cortex is the cerebrum 's (brain) outer layer of neural tissue in humans and other mammals.It is divided into two cortices, along the sagittal plane: the left and right cerebral hemispheres divided by the medial longitudinal fissure.n the human brain more than two-thirds of the cerebral cortex is buried in the sulci. The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.

Cortical Bone Definition This type of bone also known as compact bone makes up nearly 80% of skeletal mass and is imperative to body structure and weight bearing because of its high resistance to bending and torsion. Cortical bone in the spine, arms and legs can be damaged by trauma or bone disease such as osteoporosis.To treat weakened cortical bone, cortical bone grafting can be employed using synthetic bone material and other surgical implants including metal plates, screws and wires to reinforce weakened areas of the bone.ortical bone in the spine, arms and legs can be damaged by trauma or bone disease such as osteoporosis.

- Cortical homunculus. A cortical homunculus is a physical representation of the human body, located within the brain. A cortical homunculus is a neurological map of the anatomical divisions of the body. There are two types of cortical homunculi: sensory and motor.

Compact Bone Vs Spongy Bone what is the difference between the two? Best Answer: Cortical bone, also known as compact bone is one of two main types of osseous tissues. Cortical bone is dense and forms the surface of bones, contributing 80% of the weight of a human skeleton.It is extremely hard, formed of multiple stacked layers with few gaps.est Answer: Cortical bone, also known as compact bone is one of two main types of osseous tissues.

Bone Cortical bone, synonymous with compact bone, is one of the two types of osseous tissue that form bones. Cortical bone facilitates bone's main functions: to support the whole body, protect organs, provide levers for movement, and store and release chemical elements, mainly calcium.s its name implies, cortical bone forms the cortex, or outer shell, of most bones. Again, as its name implies, compact bone is much denser than cancellous bone, which is the other type of osseous tissue. Furthermore, it is harder, stronger and stiffer than cancellous bone.

Adrenocortical Carcinoma Treatment (PDQÂ®)âPatient Version Adrenocortical carcinoma is a rare disease in which malignant (cancer) cells form in the outer layer of the adrenal gland. There are two adrenal glands. The adrenal glands are small and shaped like a triangle. One adrenal gland sits on top of each kidney. Each adrenal gland has two parts.

Background Adrenal cortical adenoma is a common benign tumor arising from the cortex of the adrenal gland. It commonly occurs in adults, but it can be found in persons of any age (see the images below). Adrenal cortical adenomas are not considered to have the potential for malignant transformation.

Adrenocortical Carcinoma Treatment (PDQÂ®)âPatient Version 1 Adrenocortical carcinoma is a rare disease in which malignant (cancer) cells form in the outer layer of the adrenal gland. 2  Having certain genetic conditions increases the risk of adrenocortical carcinoma.3  Symptoms of adrenocortical carcinoma include pain in the abdomen.fter adrenocortical carcinoma has been diagnosed, tests are done to find out if cancer cells have spread within the adrenal gland or to other parts of the body. The process used to find out if cancer has spread within the adrenal gland or to other parts of the body is called staging.

Cortical reaction In most animals the extracellular matrix present around the egg is the vitelline envelope which becomes the fertilization membrane following the cortical reaction.In mammals, however, the extracellular matrix modified by the cortical reaction is the zona pellucida.This modification of the zona pellucida is known as the zona reaction. Although highly conserved across the animal kingdom, the cortical reaction shows great diversity between species.n mammals, however, the extracellular matrix modified by the cortical reaction is the zona pellucida.

What Is Cortical Cyst in the Lower Pole of Left Kidney Means 2015-06-24 06:44. A renal cortical cyst refers to a fluid-filled sac forming on the renal cortex, the outside region of the kidneys. Such as round pouch may occur in the upper pole, middle or lower pole of either kidney.
