THE PRINCIPLES OF NERVE CELL COMMUNICATION

Webb“Cell signalling is the process by which cells communicate with other cells within their body or with the external environment.” Cell signalling occurs by several distinct pathways. Multicellular organisms need cell signalling to regulate different functions. E.g. nerve cells in coordinate with muscle cells to help in body movement.

WebbIn addition to letting you consciously process the threat, your nervous system triggers involuntary responses, like an increase in heart rate and blood flow to your muscles, intended to help you cope with danger. All of these processes depend on the interconnected cells that make up your nervous system. Like the heart, lungs, and … Webb5 dec. 2024 · Not all cells are affected by the same signals. Figure 9.1. 1: In chemical signaling, a cell may target itself (autocrine signaling), a cell connected by gap junctions, a nearby cell (paracrine signaling), or a distant cell (endocrine signaling). Paracrine signaling acts on nearby cells, endocrine signaling uses the circulatory system to ... WebbFirst, within cells, electrical signals are conveyed along the cell membrane. Second, for communication between cells, the electrical signals generally are converted into chemical signals conveyed by small messenger molecules called neurotransmitters.

Webb14 feb. 2024 · A synapse is a small gap between two neurons, where nerve impulses are relayed by a neurotransmitter from the axon of a presynaptic (sending) neuron to the dendrite of a postsynaptic (receiving) neuron. It is referred to as the synaptic cleft or synaptic gap. During synaptic transmission, the action potential (an electrical impulse) …

WebbFirst, high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors —such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
