Diaphragm (optics)

In optics, a diaphragm is a thin opaque structure with an opening at its center.The role of the diaphragm is to stop the passage of light, except for the light passing through the aperture.Thus it is also called a stop (an aperture stop, if it limits the brightness of light reaching the focal plane, or a field stop or flare stop for other uses of diaphragms in lenses).

Podocyte

Nephrin is a zipper-like protein that forms the slit diaphragm, with spaces between the teeth of the zipper big enough to allow sugar and water through but too small to allow proteins through. Nephrin defects are responsible for congenital kidney failure. CD2AP regulates the podocyte cytoskeleton and stabilizes the slit diaphragm.

Neuron

A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses.The neuron is the main component of nervous tissue in all animals except sponges and placozoa.Non-animals like plants and fungi do not have nerve cells.. Neurons are typically classified into three types based on their function.

Illustration Picture of Abdominal Area

The diaphragm marks the top of the abdomen and the horizontal line at the level of the top of the pelvis marks the bottom. Connective tissue called the mesentery holds the abdominal organs together. Several large blood vessels travel through the abdomen. The aorta and inferior vena cava are two important blood vessels that lie partially in the ...

The Diaphragm

Either side of the pericardium, the diaphragm ascends to form left and right domes. At rest, the right dome lies slightly higher than the left – this is thought to be due to the presence of the liver. Fig 1.0 – The diaphragm is …

Diaphragm | Definition, Function, & Location | Britannica

diaphragm, dome-shaped, muscular and membranous structure that separates the thoracic (chest) and abdominal cavities in mammals; it is the principal muscle of respiration. The muscles of the diaphragm arise from the lower part of the sternum (breastbone), the lower six ribs, and the lumbar (loin) vertebrae of the spine and are attached to a central membranous …

Pelvic floor

The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. ... Structure. The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal.

Suprachiasmatic nucleus

The suprachiasmatic nucleus or nuclei (SCN) is a tiny region of the brain in the hypothalamus, situated directly above the optic chiasm.It is responsible for controlling circadian rhythms.The neuronal and hormonal activities it generates regulate many different body functions in …

Braced frames

Modifying the geometry of the structure can be difficult if the column bases are at different levels, as the sway imperfection varies between columns. According to 5.3.2(7) the equivalent horizontal forces have the design value of Φ N Ed at the top and bottom of each column, where N Ed is the force in each column; the forces at each end are in ...

Liver

The liver is a reddish-brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kg (3.3 lb) and has a width of about 15 cm (6 in). It is both the heaviest internal organ and the largest gland in the human body. Located in the right upper quadrant of the abdominal cavity, it rests just below the diaphragm, to the right of the …

Spleen

The spleen is an organ found in almost all vertebrates.Similar in structure to a large lymph node, it acts primarily as a blood filter. The word spleen comes from Ancient Greek σπλήν (splḗn).. The spleen plays very important roles in regard to red blood cells (erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in …

Human eye | Definition, Anatomy, Diagram, Function, & Facts

human eye, in humans, specialized sense organ capable of receiving visual images, which are then carried to the brain. The eye is protected from mechanical injury by being enclosed in a socket, or orbit, which is made up of portions of several of the bones of the skull to form a four-sided pyramid, the apex of which points back into the head. Thus, the floor of the orbit is …
