Schwann cells wrap around the AXONS of peripheral neurons.

the possible causes is when the body is loss of blood supply and cannot send information to any part of the body it collapse.

You CNS reacts in different ways to environment. For example if you are cold your brain will trigger a stimulus and give you goosebumps. Or round the other way, if you are hot then you will begin to sweat.

Neurotransmitter receptor sites on ligand-gated ion pores.

Homeostasis, dynamic equilibrium, steady state, coordination, regulation, human body, and heart. It can be disrupted by parasites, fungi, bacteria and viruses.

It's the brain. the brain controlls everything and is apart of the core nervus ststem. and there it collects all the information.

I came on this to figure it out!

Mixed nerves like the spinal nerves have both sensory afferents and motor efferents.

The nervous system controls breathing rate.

Firstly your receptor cells pick up a stimuli and sends an electrical impulse along the sensory neurone's axon to the spinal cord.the impulse is then passed onto the relay neurons IN the CNS(the spinal cord decides what to do but the brain is also informed).

The relay neurone then passes the command from the spinal cord in the form if an impulse to the motor neurone.the impulse travels along its axon to the effector.

Hope it helps

P.S. •relay neurones exist only within the CNS and not outside it.

•reflex arcs take the shortest possible route

Somatic nervous system: Associated with the voluntary control of body movements via skeletal muscles Autonomic nervous system:operates independently of voluntary control, although certain events, such as emotional stress, fear, sexual excitement, and alterations in the sleep-wakefulness cycle, change the level of autonomic activity.

Sensory neurons

The neurotransmitter for sympathetic nervous system is norepinephrine (or also called noradrenaline) that acts on adrenergic receptors of the effector organ (alpha 1, beta 1, beta 2 receptors). The adrenergic receptors are G-protein coupled.

The effect upon the target neuron is determined not by the source neuron or by the neurotransmitter, but by the type of receptor that is activated. A neurotransmitter can be thought of as a key, and a receptor as a lock: the same type of key can here be used to open many different types of locks. Receptors can be classified broadly as excitatory(causing an increase in firing rate),inhibitory(causing a decrease in firing rate), or modulatory(causing long-lasting effects not directly related to firing rate).

Opium

A psychotropic drug acts primarily on the central nervous system (CNS), where it produces temporary changes affecting the mind, emotions, and behavior. These drugs are used as medications to control pain, and to treat narcolepsy and attention disorders.

In the nervous system, electrical signals travel throughout the brain and into the body via nerves and nerve fibers. Electrical signals are how the brain tells the body what it should do.

1. you bend down .2. you pull his pants down.

3. you suck that dick good .

4. pull his pants back up

5. whip your face bc its full of cum.

6. you smile.

The central nervous system consists of the brain and the spinal cord. It essentially integrates the information it receives from all parts of the human body.

You have acetylcholine liberated at ganglion in both sympathetic and parasympathetic nervous system. You have noradrenaline secreted at post ganglionic sympathetic nerve terminals. You have acetylcholine secreted at post ganglionic parasympathetic nerve terminals.

The largest single part of the dogfish shark nervous system is the brain. It gets messages from the neurons and sends responses to the rest of the body.

Bone is quite different from nerve tissue. It is not an excitable tissue.
