1. Receiving Information:
#### a. Dendrites:
Dendrites are branched extensions of neurons that act like antennas to receive messages from neighboring neurons. They convert these messages into small electric impulses and transmit them inward, toward the main body of the neuron.

Dendrites are crucial for receiving information from other neurons. They are highly branched extensions that propagate the electrochemical stimulation received from other neural cells to the cell body of the neuron. The branching structure of dendrites increases the surface area available for receiving signals, allowing a neuron to receive input from many other neurons. These structures play a critical role in integrating synaptic inputs and determining the extent to which action potentials are produced by the neuron. Below is a diagram illustrating the structure of dendrites and their function in a neuron.



#### b. Synaptic Transmission:
Synaptic transmission, or neurotransmission, is the process by which signaling molecules called neurotransmitters are released by a neuron (the presynaptic neuron), and bind to and activate the receptors of another neuron (the postsynaptic neuron). This process occurs at specialized junctions called synapses. When an action potential reaches the axon terminal of the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft, the small gap between the neurons. These neurotransmitters then bind to receptors on the dendrites of the postsynaptic neuron, initiating a new action potential, or inhibiting one, in the postsynaptic neurons. Below is a diagram illustrating the basic model of neurotransmission:
