- The mammary glands will be examined with the female reproductive system. The sensory receptors in the skin, such as Meissner's and Pacinian corpuscles, as well as free nerve endings, are classified as general sensory receptors.ther members of this group of receptors include free nerve endings in the connective tissue, as well as the muscle spindle and Golgi tendon organ found in the musculoskeletal system. Special sensory receptors have specific anatomic locations.

- It is divided into two subgroups; the single-unit (unitary) and multiunit smooth muscle. Within single-unit cells, the whole bundle or sheet contracts as a syncytium (i.e. a multinucleate mass of cytoplasm that is not separated into cells).

RIXIMKA DUMARKA The corpus luteum (Latin for yellow body; plural corpora lutea) is a temporary endocrine structure in female ovaries that is involved in the production of relatively high levels of progesterone, moderate levels of estradiol and inhibin A.[1] It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation.[2] ...

Mechanoreceptor Lamellar corpuscles, or Pacinian corpuscles, are pressure receptors located in the skin and also in various internal organs. Each is connected to a sensory neuron. Because of its relatively large size, a single lamellar corpuscle can be isolated and its properties studied.n glabrous (hairless) skin, there are four principal types of mechanoreceptors, each shaped according to its function. The tactile corpuscles (also known as Meissner corpuscles) respond to light touch, and adapt rapidly to changes in texture (vibrations around 50 Hz).

Mean corpuscular volume Mean corpuscular volume The mean corpuscular volume, or mean cell volume (MCV), is a measure of the average volume of a red blood corpuscle (or red blood cell). The measure is attained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit), and dividing that product by the number of erythrocytes (red blood cells) in that volume.

Trigeminal ganglion Trigeminal ganglion. The trigeminal ganglion (or Gasserian ganglion, or semilunar ganglion, or Gasser's ganglion) is a sensory ganglion of the trigeminal nerve (CN V) that occupies a cavity (Meckel's cave) in the dura mater, covering the trigeminal impression near the apex of the petrous part of the temporal bone.

What Is The Striatum? The corpus striatum, a macrostructure which contains the striatum, is composed of the entire striatum and the globus pallidus. The lenticular nucleus refers to the putamen together with the globus pallidus.

Corpus Luteum - Anatomy & Physiology The Corpus Luteum is an endocrine structure. The luteal cells are steroidogeneic producing hormones of the luteal phase of the oestrus cycle; progesterone, oxytocin and relaxin. Progesterone prepares and maintains the uterus for implantation of the fertilised ovum.

Severe Weather Glossary A complex of thunderstorms which becomes organized on a scale larger than the individual thunderstorms, and normally persists for several hours or more. MCSs may be round or linear in shape, and include systems such as tropical cyclones, squall lines, and Mesoscale Convective Complexes (MCCs) (among others). MCS often is used to describe a cluster of thunderstorms that does not satisfy the size, shape, or duration criteria of an Mesoscale Convective Complex.

- noun (plural syncytia sɪnˈsɪtɪə). 1 A single cell or cytoplasmic mass containing several nuclei, formed by fusion of cells or by division of nuclei. Example sentences. 1  The maze experiments used the plasmodium phase of the mould, a multi-nucleate single cell, or syncytium. In the early Drosophila embryo, the male and female pronuclei fuse and then undergo 13 rounds of synchronous mitoses without cell division to produce a syncytium.

Ehlers Danlos Syndrome Ehlers-Danlos syndrome (EDS) is a group of hereditary connective tissue disorders characterized by defects of the major structural protein in the body (collagen). Collagen, a tough, fibrous protein, plays an essential role in holding together, strengthening, and providing elasticity to bodily cells and tissues.hlers-Danlos syndrome (EDS) is a group of hereditary connective tissue disorders characterized by defects of the major structural protein in the body (collagen).

Nissl body Nissl body topic. Motor nerve cell from ventral horn of medulla spinalis of rabbit. The angular and spindle-shaped Nissl bodies are well shown. A Nissl body , also known as Nissl substance , is a large granular body found in neurons . These granules are of rough endoplasmic reticulum (RER) with rosettes of free ribosomes , and are the site of protein synthesis.

Syncytium Another important vertebrate syncytium is in the placenta of placental mammals. Embryo-derived cells that form the interface with the maternal blood stream fuse together to form a multinucleated barrier-the syncytiotrophoblast.

Pacinian corpuscle In 1831, while dissecting a hand, he observed the corpuscles around the branches of the median nerve to the digits. These corpuscles, now known as Pacinian corpuscles, had been originally described in 1741, but Pacini was the first to describe their distribution in the body, their microscopic structure, and their nerve connections. He also related the function of the corpuscles to the sensation of touch and deep pressure.

Gerstmann-Straussler-Scheinker disease Gerstmann-Straussler-Scheinker disease (GSS) is a type of prion disease. Prion diseases are a group of conditions that affect the nervous system. The main feature of GSS is a progressive degeneration of the cerebellum (a part of the brain that controls coordination, balance, equilibrium and muscle tone), as well as different degrees of dementia.
