Retinal damage (from ...

Neuron

... cord and in the nerves and ganglia of the peripheral nervous system . Contents ... central nervous system and Schwann cells in the peripheral nervous system. The myelin sheath in peripheral nerves normally runs along the axon in sections ...

Punctuated equilibrium

... include if most evolution occurs by speciation in peripheral isolates? ... In any local area inhabited by ... should appear suddenly by migration from a peripheral region in which it evolved. In the peripheral region itself, we might find direct evidence of ...

Nervous system

... animals are often divided into a central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord . ... actually axonal processes of nerve cells) are considered to be PNS. The peripheral nervous system can also be roughly seen as consisting of sensory pathways ...

Peripheral membrane protein

... peripheral membrane proteins are proteins that adhere only loosely to the ... channels and transmembrane receptors , for example, may be defined as peripheral membrane proteins. These proteins, in contrast to integral membrane ...

Axon

... generally, the axons of many neurons are sheathed in myelin , which is formed by either of two types of glial cells : Schwann cells ensheathing peripheral neurons and oligodendrocytes insulating those of the central nervous system . Along myelinated nerve fibers, gaps in the sheath known as nodes ...

Biological tissue

... filaments that move past each other and change the size of the cell. Nervous tissue - cells forming the brain , spinal cord and peripheral nervous system Examples of tissue in other multicellular organisms are vascular tissue in plants , such as xylem and phloem . Plant ...

Full blood count

Cell membrane

... may function as channels or transporters across the membrane, or as receptors. Some of these proteins simply adhere to the membrane ( extrinsic or peripheral proteins), while others might be said to reside within it or to span it ( intrinsic proteins -- more at integral membrane protein ). ...

Glucose

... for the less reactive cyclic isomer . Nevertheless, many of the long-term complications of diabetes (e.g., blindness, kidney failure, and peripheral neuropathy) are probably due to the glycosylation of proteins. The chain form of D -Glucose In respiration, through a series of ...

Intermediate filament

Stem cell

... have been taken from the blood instead of the bone-marrow, making the procedure safer for older people. Although normally scarce, the number of peripheral blood cells can be increased by a course of drugs, which release the stem cells from the bone-marrow. These are removed before chemotherapy, which ...
