The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.

has two major divisions: the somatic nervous system and the autonomic nervous system.

The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS.

• Sensory Neurons- PNS carries info from the PNS to the CNS.
• Interneurons- CNS most membranes- Carries info with in the CNS*
• Motor Neurons- PNS carries info from the CNS to the PNS (organs, glands, etc)

The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts. The nerve is responsible for certain sensory activities and motor information for movement within the body.

Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

The peripheral nervous system’s main job is to send information gathered by the body’s sensory receptors to the CNS as quickly as possible. Once the CNS has understood the information, the PNS will relay the specific orders back out the body.

the CNS is the control center, brain and spinal cord. The PNS is nerve fibers that carry information to and from the CNS. White matter is myelinated fibers and is in the inside of the brain and outside of spinal cord.

The CNS is the brain and spinal cord. The PNS is everything else. Functionally, the nervous system can be divided into those regions that are responsible for sensation, those that are responsible for integration, and those that are responsible for generating responses.

Peripheral neuropathy can result from traumatic injuries, infections, metabolic problems, inherited causes and exposure to toxins. One of the most common causes is diabetes.

You may experience the sudden onset of one or more symptoms, such as: Numbness, tingling, weakness, or inability to move a part or all of one side of the body (paralysis). Dimness, blurring, double vision, or loss of vision in one or both eyes. Loss of speech, trouble talking, or trouble understanding speech.

Which of the following is a similarity between the central nervous system and the peripheral nervous system? Their structures are composed of neurons and neuroglia.

Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.

The signs of nerve damage

• Numbness or tingling in the hands and feet.
• Feeling like you’re wearing a tight glove or sock.
• Muscle weakness, especially in your arms or legs.
• Regularly dropping objects that you’re holding.
• Sharp pains in your hands, arms, legs, or feet.
• A buzzing sensation that feels like a mild electrical shock.

Brain and nervous system problems are common. These neurological disorders include multiple sclerosis, Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke, and can affect memory and ability to perform daily activities.

Nervous system diseases

• Alzheimer’s disease. Alzheimer’s disease affects brain function, memory and behaviour.
• Bell’s palsy.
• Cerebral palsy.
• Epilepsy.
• Motor neurone disease (MND)
• Multiple sclerosis (MS)
• Neurofibromatosis.
• Parkinson’s disease.

5 Common Neurological Disorders and How to Identify Them

1. Headache. Headaches are one of the most common neurological disorders—and there are a variety of different kinds of headaches, such as migraines, cluster headaches, and tension headaches.
2. Stroke.
3. Seizures.
4. Parkinson’s Disease.
5. Dementia.

Headaches Headaches are one of the most common neurological disorders and can affect anyone at any age.

Neurological Disorders

• Acute Spinal Cord Injury.
• Alzheimer’s Disease.
• Amyotrophic Lateral Sclerosis (ALS)
• Ataxia.
• Bell’s Palsy.
• Brain Tumors.
• Cerebral Aneurysm.
• Epilepsy and Seizures.

There are many types of dementia, including frontotemporal dementia, Lewy body dementia and vascular dementia, but Alzheimer’s disease is the most common and perhaps the best known.

Creutzfeldt-Jakob disease (CJD) is an extremely rare, degenerative brain disorder. It affects about one in every million people per year worldwide.

Signs and symptoms of nervous system disorders

• Persistent or sudden onset of a headache.
• A headache that changes or is different.
• Loss of feeling or tingling.
• Weakness or loss of muscle strength.
• Loss of sight or double vision.
• Memory loss.
• Impaired mental ability.
• Lack of coordination.
