What is synaptic transmission​

Sagot :

Answer:

Synaptic transmission is the process by which information is communicated between two neurons in the nervous system. It is the fundamental process by which the nervous system works.

When one neuron stimulates another neuron, it releases a neurotransmitter, which binds to receptors on the target neuron's cell membrane, resulting in a chemical signal. This chemical signal triggers a series of events inside the target neuron's cell that ultimately causes it to transmit a signal to other neurons, which then transmit the information to more neurons, and so on.

Synaptic transmission is essential for our ability to sense, think, move, and perceive our environment. It allows us to learn, remember, and communicate with each other, and is the basis of how our nervous system functions.

Explanation:

shorten it if it's too long for you, or just pick one paragraph for you and thank me later.

Synaptic transmission is the process by which nerve cells (neurons) communicate with each other through synapses, which are specialized junctions between neurons.

Characteristics of Sypnatic Transmission

  • Chemical or Electrical Signals - Synaptic transmission can be chemical or electrical. In chemical synapses, neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, causing a response. In electrical synapses, the electrical signal directly passes through gap junctions between neurons.
  • Unidirectional Flow - Transmission across a synapse is typically unidirectional. The signal travels from the presynaptic neuron, which releases neurotransmitters or electrical signals, to the postsynaptic neuron, which receives and responds to the signal.
  • Synaptic Plasticity - Synaptic transmission can be modulated by synaptic plasticity, which involves changes in the strength or efficacy of synaptic connections. This plasticity is crucial for learning, memory, and adapting to new experiences by adjusting the response of the postsynaptic neuron based on past activity.
