What is the most significant neurotransmitter in the basal ganglia?
What is the most significant neurotransmitter in the basal ganglia?
dopamine
Sodium enters the cell and causes depolarization. A small amount of potassium also leaves the motor end plate. This means binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate.
calcium
What do neurons have to do with emotions?

Urination
The nervous system consists of the brain which brings throughout your body Theirs two parts of the nervous system, the cetral nervous system, and the peripheral nervous system. The central nervous system contains the brain, spinal cord, and retina. The peripheral nervous system consists of sensory neurons, clusters of neurons called ganglia, and nerves connecting them to each other and to the central nervous system.
What is the division of the peripheral nervous system that communicates with smooth muscle?
Autonomic Nervous System
a resting potential
Does CPR take over the respiratory and nervous systems of the body?

How does lead poisoning affect children?

How many Brain cells do you have in your Brain?
They have one brain divided into four lobes.
- Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
- Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
- Occipital Lobe- associated with visual processing
- Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech
