Nervous System

The nervous system does not tell muscles how to react. The nerves transmit electrical pulses that make muscles contract. Different nerves attached to different muscles strands control how a muscle reacts. For example, nerves going to some arm muscles when they contract may make your elbow bend. Nerves going to a different set of muscles when made to contract may make your arm straighten out at the elbow. Using all muscles in that area allows you to maintain a bent elbow in a specific position.

The nervous system is a system in the body that relates to the brain, spinal cord, sensory organs and nerves.

Yes if severe enough.

You have separate sensors for each aspect - except pain.

(And separate nerves for each sensor)

Pain is NOT a sensation, it is a synthesis generated in the brain from the sum of all input signals.

The frontal lobe is associated with personality.

The structure in the ear that sends impulses to the brain regarding body motion and position is the vestibular system, specifically the semicircular canals and otolith organs. These structures detect changes in head position and movement through fluid movement and the displacement of tiny hair cells. The resulting signals are then transmitted to the brain, allowing it to maintain balance and spatial orientation.

Nerves are like trees. The have branches call axons.

The human nervous system transmits an estimated 100 billion messages daily. These messages, conveyed through neurons via electrical impulses and chemical signals, facilitate communication between the brain and various body parts. This intricate network allows for the coordination of numerous functions, from reflexes to complex cognitive processes. The sheer volume underscores the nervous system's critical role in maintaining bodily functions and responding to the environment.

optic nerve cells.

The brain controls water balance, body temperature, and the endocrine system.

I beleive it is a Voltage moving down the dendrites (not a Current) which is caused by the sodium and potassium ions I think. I just remember something about that from a book i read once.

Contray to the belief, the medulla oblongata in a structre of the brain stem that contols autonomic functiopns like respiration, blood pressure, cardiac function, various bodily secretions, swallowing, coordintaion of body movement and reflexes. The medulla oblongata helps in the transferring of messages between various parts of the brain and the spinal cord.

I believe the correct structure that controls emotions is the amygdala.

Nervus trigeminus (V)

All this means is that the part of skin you are pushing on the nervous tissue is communicating with somewhere else in your body and when you push on that part of skin it will tell the place that it is communicating with that it is feeling pressure.

The "RER" is the Rough Endoplasmic Reticulum, also known as Nissle Bodies. They are structures within the cell where protein synthesis occurs in ribosomes, which cover the endoplasmic reticulum giving it a "rough" appearance under a microscope. In the nervous system, the rough endoplasmic reticulum is found within the cell body of a nerve. Neuropeptides are synthesised and partially processed there. They are thought to be involved in the synthesis of neurotransmitters such as acetycholine.

I think it is the Brain....

Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.

Yes. you can have a Meningioma of the Optic Nerve.

Yes, the nerves are part of the nervous system.
