Nervous System
This category is for questions about the mechanical and chemical process of reactions to internal and external stimuli, ranging from the brain down to the spinal cord, and all nerves, cells and tissues in between.

In the human nervous system what is synapse?
It is the junction between terminal part of one axon and the dendrite of the adjacent neuron .Synapse helps in the transmission of impulses from one neuron to another neuron.
What is the neuron that carries impulses away from the central nervous system?
sensory neurons trust me i know this one for sure i went on over 29 websites to find this out
What makes up the automatic nervous system?
I think you mean the 'Autonomic' nervous system. It is responsible for regulating internal organs, among other things.
What is the Alternative name for sensory nerve ending?
The other name for the sensory nerve is sensory neuron. These are nerve cells that transmit sight, sound, and feelings.
What are neurotransmitters which are found in the nervous system?
Nerve/command signals are sent from one place to another in the body through conductors called nerve fibers. These conductors can hand-off/relay these signals to other nerve fibers, or to organs, such as muscles, that take action on the command. Neurotransmitters are chemical substances located where the nerve hands off these signals. They enable the signal to pass the nerve carrying the signal to the receiving fiber.
What germ layer does the tissue of the peripheral nervous system develop from?
All nervous tissue arise from ectoderm. Whether central or peripheral. It is anatomical division. Functionally all nervous cells are connected to each other.
Which of the following is a way in which somatic and autonomic nervous systems are similar?
The somatic nervous system is the voluntary part of the brain and it operates under conscious control. The autonomic nervous system is the part of the brain that is involuntary, and that humans have no control over.
How can brains and nerves send signal to your body?
The brain can get signals, add them up, and signal back for action in a split second. Different parts of the brain do different things.
The medulla, at the top of the signal cord, controls nerves that are in charge of certain muscles and glands. The medulla keeps your heart beating, your lungs taking in air and your stomach digesting food.
The cerebellum controls body movement and balance. The cerebellum is where is where thinking, learning, remembering, deciding and awareness take place. The sensation of seeing, smelling, tasting and touching are centred here. So are the body feelings.
The so far have learnt that the messages travel through the nervous system -to and from the brain- are weak electrical charges. The billions of nerve cells in the body form a huge network that leads to the spine. Along the way, nerves from different parts of the body come together in thick bundles. A thick cable of nerves runs up the hollow of the spine to brain. One set of the nerves in the cable carries messages from senses to brain. Another set carries messages from the brain to the muscles and glands. The brain sorts out the signals and makes the right connections.

What is called the study of nervous system its functions and disorder?
Neurology is the study of the nervous system, including the brain.
What type of movement does the autonomic system control?
The somatic nervous system regulates skeletal muscle tissue, while the ANS services smooth muscle, cardiac muscle, and glandular tissue.
What jobs does the nervous system have?
The nervous system works with the endocrine system to maintain homeostasis in our bodies.
Which neurotransmitter is involved with mood weight regulation and sleep induction?
gamma-amino butyric acid
The sympathetic nervous system.
The sympathetic nervous system is the part of the autonomic nervous system that arouses the body and is involved in the "fight or flight" response.
sympathetic nerves
What would be the effect of low blood protein levels on the colloidal pressure?
If blood protein levels become low, then there will be a decrease in colloidal osmotic pressure. This in turn can cause side effects in the body like edema and muscle degeneration.
What comprise the two primary divisions of the nervous system?
The nervous system can be divided into two components in several ways.
First, you can divide the nervous system into central (brain and spinal cord) and peripheral (the rest of the nerves).
Second, you can divide the system into autonomic and voluntary.
Third, you can divide the system into sympathetic and parasympathetic.
