Witryna12 lut 2024 · Cells within these organs produce and contain hormones in intracellular granules or vesicles that fuse with the plasma membrane in response to the appropriate signal. This action releases the hormones into the … WitrynaThe nervous impulses travel through the motor neurone to the muscle in the leg, which acts as the effector. Finally, the muscles contract, causing the leg to jerk up and away from the pin. ... Both words refer to actions that you have no biological control over, such as hiccuping and shivering. The difference between them is that unconscious ...

WitrynaThe relay neurone connects to the motor neurone (and also sends a message to the brain). Motor neurone sends impulses to effector. Effector produces a response …
WitrynaNerve impulse refers to a signal driven by either electrical, chemical or mechanical stimulus onwards the segment of an axon filament. It generates a change in the potential gradient of voltage-gated channels across the membrane, resulted from ionic movement in and out of the axolemma. WitrynaInformation from receptors passes along neurones, as electrical impulses to co-ordinators such as the central nervous system or CNS. The CNS is the brain and …
WitrynaThey are moved in and out of the cell through sodium and potassium channels and sodium-potassium pump. Conduction of nerve impulse occurs due to the presence of …
Witryna29 lip 2024 · Axons are very thin nerve fibers that carry nerve impulses away from a neuron (nerve cell) to another neuron. A neuron is responsible for receiving sensory input, sending motor commands to your muscles, and transforming and relaying the electrical signals throughout these processes.
