Nervous System

Yes, when consumed by man, the narcotics act on the central nervous system. The narcotics acts on the central nervous system that leads to lack of coordination of the various body parts.

The saccule and utricle are parts of the inner ear. They're in the bony labyrinth of the vestibule.

The somatic and autonomic nervous systems. The somatic nervous system has nerves that connect voluntary skeletal muscles and sensory receptors. It is made of afferent nerves that carry info to the CNS and efferent fibers that carry neural impulses away from the CNS. The autonomic system, mediates physiological arousal. This system has two components: the sympathetic nervous system that mobilizes the body to respond to emergencies and the parasympatheic nervous system that helps conserve the body's energy and helps return the body back to normal activity after an emergency.

Any internal or external change that brings about a response is called a stimulus. As a key homeostatic regulatory and coordinating system, the nervous system detects, interprets, and responds to changes in external and internal conditions.

It is true that drugs and alcohol can affect the mind It can also interfere with the central nervous system.

The respiratory system and the circulatory (cardiovascular) system.

A) vagus nerve (X)

B) facial nerve (VII)

C) glossopharyngeal nerve (IX)

D) trigeminal nerve (V)

E) facial nerve (VII), vagus nerve (X), and glossopharyngeal nerve (IX)

Answer is E

The nervous system can send messages to the Neorons then to your brain. Such as when you touch something hot your sensory cells send a message to your brain to react to take your hand off the hot object.

For a female, her clitoris houses a vast amount of nerves compared to other parts of her body. For a man, the head of the penis is ultra-sensitive and nerve-filled. For both sexes, ears and earlobes contain a lot of nerves as well.

There are three layers of connective tissues protecting the brain and spinal chord called meninges. the outermost layer is the dura mater, then the arachnoid mater, thhen the subarachnoid pia mater.

No. It is an autonomic reflex. You brain doesn't even resister that you sneezed for a millisecond after it happened.

The human body, in its optimal condition, is capable of selecting the most appropriate molecules to rebuild a nerve. So eat in moderation a wide variety of foods and do gentle exercise. Nerves can take up to 2 years to rebuild, but they have a remarkable ability to heal. Don't forget to get ample, regular sleep.

No that's the circulatory system

D. Cerebellum \ It functions as a regulator of timing of movements. It integrates sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex - which sends information to the muscles causing them to move - and the spinocerebellar tract - which provides feed-back on the position of the body in space (proprioception). The cerebellum integrates these pathways, using the constant feed-back on body position to fine-tune motor movements. Studies of motor learning in the vestibulo-ocular reflex and eyeblink conditioning demonstrate that the timing and amplitude of learnt movements are encoded by the cerebellum

WELL the digestive system does absolutly nothin =). to keep your body healthy eat junk food and ice cream. ice cream is dairy products which are healthy, and potato chips are vegetables! see? healthy

by sending weak electrical pulses through our system. that is also one of the reasons our spine is important, because the electrical pulses are sent through it and it they stop thats when we stop being able to fully use the lower half of our body

It is caused by our brain's interpretation and reaction to the sensations of spinning motion generated by the Vestibular System of the inner ear, the Visual System's reaction to motion and the body's signals from the Skeletal System (especially the joints) indicating motion.

Our ears do more than hear. Our sense of balance is a second function of our inner ears. There are places in the inner ear that have a fluid inside, and as you move your head and body, this gel-like liquid sloshes around and moves against some tiny cilia (hair like cells). When these hairs move due to the movement of the fluid (which is caused by changes in forces on the fluid, like gravity), our brain uses these movements to interpret the body position and adds to the other senses that we use in our spatial sense. Then we can tell how we are oriented, so we can walk and balance our bodies.

There is another part of the system of balance that is in the inner ear that can also tell the brain whether we are sitting up, leaning back, or lying down, based upon the position of our head. This part uses little "stones" that move with the motion of our heads to keep track of this body positioning.

The part of the ear that works to help us keep our balance is called the Vestibular System. It includes an area known as a labyrinth, that is a maze of tubes that hold the cilia and fluids. It is on the opposite end of the labyrinth from the cochlea, which is the part of the inner ear that allows us to hear.

Along with the movement of the fluid, other signals from our bodies also are included in the brain's analysis and fine tuning of our senses of motion, movement, position, and balance. These other signals come from the eyes and vision, and also from movement and forces on the joints and skeleton (mostly in our feet and legs) that orient us to our vertical position. Our brains react to the sensations of spinning movement with safety features that create the symptom of dizziness, this will usually make us stop the the motion and lie down where we cannot be thrust against things or fall and hurt ourselves.

The Peripheral Nervous System plays a key role in our everyday lives. It controls so much of our body and is the biggest system inside the body.

The PNS, or Peripheral Nervous System is made up of neurons, a type of nerve cell. They are found often clumped in bundles, but aren't touching.

The Pns is made up of two systems:

The Sonmatic Nervous System, which controls all voluntary reactions, and the Autonomic Nervous System which controls involuntary reactions.

You can take care of the senses and the nervous system by eating foods that are high in B vitamins. These are known to support the nervous system and senses.

The two main divisions of the nervous system is the Central Nervous System (CNS), and the Peripheral Nervous System (PNS).

The CNS is made up of the Brain, Brain Stem and the Spinal Cord.

The PNS is made up of the Sensory and Motor nerves connecting to the spinal cord (and in some parts the brain).

There is also another system called the Endocrine System which can independently control digestive functioning, but that's a bit more advanced and usually isn't taught till you reach University/College.

If you want some more reading 'thinkquest' has a good tutorial.

not sure , but i think they are called motor neurons and they are part of the PNS system

Central Nervous System of the brain

When a nerve impulse (action potential) arrives at a synapse, calcium ions are absorbed into the neuron. they stimulate the synaptic vesicles, containing neurotransmitter, to fuse with the cell membrane and release the neurotransmitter into the synapse.

The brain is the main organ in the nervous system. It is connected to the spinal cord to send messages through your nervous system to the rest of your body. Your nervous system is very sensitive it hurts when you touch it.
