Alcohol is a dpressant. A depressant is: anything that reduces functional or nervous activity. Alcohol blocks some of the messages that travel to the brain. This changes a person's perceptions, emotions, movement, vision, and hearing.
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.
Communication in the nervous system depends on the transmission of electrical impulses, known as action potentials, that travel along the length of neurons. These electrical signals allow for the rapid and precise transmission of information from one neuron to another, enabling various functions such as sensory perception, motor responses, and cognition.
A neuron is the primary agent that is capable of initiating nervous impulses. When a stimulus is received, specialized structures in the neuron, called dendrites and axons, allow for the transmission of electrical signals to communicate and trigger nervous impulses.
The nervous system controls muscles and glands by electrical impulses.

Neurons are the cell type responsible for the transmission of electrochemical impulses within the nervous system. These specialized cells are capable of transmitting signals through electrical and chemical processes along their axons.
Electrical impulses move across axons in the nervous system.
Nervous tissue, specifically neurons, carry electrical impulses from the brain to other parts of the body. These neurons transmit information in the form of electrical signals known as action potentials.
The nervous system, specifically the brain and spinal cord, directs how and when muscles move through the transmission of electrical signals called nerve impulses. These impulses travel along motor neurons from the central nervous system to the muscles, triggering muscle contraction and movement.
Axonal transmission is the process by which electrical signals are transmitted along the axon of a neuron. It involves the propagation of action potentials, or electrical impulses, from the cell body of the neuron to the axon terminals where neurotransmitters are released. This process is essential for communication between neurons in the nervous system.
The two types of structures that carry out transmission functions are nerve fibers, which transmit electrical impulses in the nervous system, and axons, which are extensions of nerve cells that conduct electrical signals away from the cell body.
Animal cells specialized for conducting electrochemical impulses are known as neurons. Neurons have unique structures such as dendrites, axons, and synapses that allow for the transmission of electrical signals within the nervous system.
