Part of a global family: Over the course of their exchange year and beyond, the student becomes much more than a guest in their host family's home; they're part of one big global family. Host Family Application: Families who express an interest in hosting are guided through an application process by a local exchange coordinator in their community and EF staff in our Boston office.
An axon (from Greek á¼Î¾ÏÎ½ axÅn, Ã¡xÅn), axis is a, long slender projection of a nerve, cell or, neuron that typically conducts electrical impulses away from the'neuron s cell. Body myelinated axons are known as nerve. Fibers the function of the axon is to transmit information to different, neurons muscles and. glandshen an action potential reaches a presynaptic terminal, it activates the synaptic transmission process. The first step is rapid opening of calcium ion channels in the membrane of the axon, allowing calcium ions to flow inward across the membrane.
Endocrine and exocrine glands secrete various products. These include hormones, enzymes, metabolites, and other molecules. In exocrine glands, products of these cells collect in the duct of the gland and flow toward the surface to which the duct is in contact.Since endocrine glands lack ducts, the product is released across the cell membrane into interstitial spaces around the cells.odes of Secretion. Secretory cells of exocrine glands release their products into ducts in three different ways. The mode of secretion can be classified as merocrine, apocrine, or holocrine. Cells that secrete products via the merocrine method form membrane-bound secretory vesicles internal to the cell.
