WebMar 5, 2024 · A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium ions to flow back into the cell.

Nervous System Control of Muscle Tension – Anatomy & Physiology
WebYour hypothalamus, a structure deep in your brain, acts as your body’s smart control coordinating center. Its main function is to keep your body in a stable state called homeostasis. It does its job by directly influencing your autonomic nervous system or by managing hormones. Many conditions can damage your hypothalamus, which can affect ... WebIt is brought about by the nervous system after it detects any physical response on any part of the body due to various changes such as temperature, pressure, light, etc. Furthermore, the nervous system coordinates with the endocrine system to react accordingly. WebApr 12, 2024 · The action potential generates at one spot of the cell membrane. It propagates along the membrane with every next part of the membrane being sequentially depolarized. This means that the action potential doesn’t move but rather causes a new action potential of the adjacent segment of the neuronal membrane. onebe francis
