The main function of sensory nerves is to carry sensory information from the body to the spinal cord. This information is then processed by the spinal cord and sent to the brain, where it is interpreted. Sensory nerves also carry signals from the brain to the body, allowing us to move and respond to our …
1. Chemical synapse: This type of synapse is the most common and involves chemical signaling between two neurons. 2. Electrical synapse: This type of synapse is less common and involves electrical currents passing through gap junctions between the two neurons. 3. Gap junction: This type of synapse is formed when two neurons are connected by …

Neurotransmitters are chemical messengers that enable the transmission of signals between neurons and other cells in the body. They are essential for the functioning of the nervous system and are involved in a variety of processes, including learning, memory, emotion, mood, and movement. Neurotransmitters are also involved in the regulation of appetite, sleep, and stress. …

A synapse is the small gap between two neurons that allows them to communicate with each other. When an impulse (action potential) is generated in one neuron, it is transmitted across the synapse to the next neuron. This is done by a process called neurotransmission. Neurotransmitters are released from the presynaptic neuron and bind to …

The structure of a synapse consists of three parts: a presynaptic terminal, a postsynaptic terminal, and the synaptic cleft. The presynaptic terminal contains neurotransmitter-filled vesicles, while the postsynaptic terminal contains receptor proteins that bind to neurotransmitter molecules released by the presynaptic terminal. The synaptic cleft is the gap between the presynaptic and postsynaptic terminals, and …
A synapse is a junction between two nerve cells, or between a nerve cell and a gland or muscle. It is a specialized junction that allows a signal to pass from one cell to another. The signal is usually an electrical or chemical one, and is transmitted across the synapse when a neurotransmitter is released …
A nerve impulse is a wave of electrical activity that travels along the length of a nerve cell. It is generated by the movement of ions across the nerve cell membrane and is the main method of communication between nerve cells. The nerve impulse begins when a stimulus, such as a touch or a sound, …
When ions are stimulated, their charges may change. For example, when an atom gains or loses electrons, its charge changes. If an atom gains electrons, it becomes more negatively charged and if it loses electrons, it becomes more positively charged.
The charges on either side of the plasma membrane are defined by the distribution of ions across the membrane. These ions include sodium, potassium, chloride, and other small molecules. The inside of the cell is typically more negative than the outside due to the presence of anionic proteins and other negatively-charged molecules, while the outside …
1. Insulation: Myelin sheaths insulate nerve fibres, allowing them to transmit nerve impulses quickly and efficiently. 2. Support: Myelin sheaths also provide physical support to the nerve fibres they surround, protecting them from damage. 3. Maintenance: Myelin sheaths are responsible for maintaining the structural integrity of the axon. 4. Metabolic support: Myelin sheaths provide metabolic …
