Many readers are interested in the right subject – the peripheral nervous system. We are happy to report that the manufacturer has already done a study of current research on your fascinating subject. Informed by the latest medical reports, advanced research papers, and example studies, we offer a wide range of answers. Keep reciting to recognize more.
Human nervous system It is very difficult and is generated from the spinal cord, brain, and trillion neurons. They are responsible for performing a variety of important functions, such as receiving messages, interpreting them, and returning to effector websites. The nervous system Maintains coordination with the external environment and the functions of internal organs. Nervous System system Can be subdivided into two main divisions and vegetative. nervous system (CNS) and peripheral nervous system (PNS).
The PNS consists of the outer nerves of the brain and the spinal cord with neurons. They coordinate with the central nervous system when they receive and transmit reports. Unlike the brain and spinal cord, the nerves of the PNS are not protected by cavities or membranes because they are why peripheral nervous system more vulnerable to toxic and mechanical trauma.
Part of the human nervous system
- Central nervous system : Central nervous system It consists of the brain and spinal cord. It regulates the most important functions of the body, including thermal control, appetite control, mood regulation, impressions, and thought.
- Peripheral nervous system It is produced by the central nervous system, the nerves nervous system throughout the hull.The PNS is intentionally created by
- 31 pairs of spinal nerves (connected to the spinal cord).
- 12 pairs of cranial nerves (attached to the skull).
In the peripheral nervous system There are two types of cells Sensory. nervous Cells that send information to the CZS and motors. nervous Cells bring information from the CZ to organs throughout the body. Motor. nervous system Can be further subdivided. two systems :
- Autonomic nervous system This is an unwilling type of nervous system whereby the body’s movements and effects are not themselves regulated. the ANS primarily helps maintain digestive function system breathing mechanism, heart beat, etc.
- Somatic nervous system : Somatic nervous system It is responsible for the merger of the nerves of the skin and the muscles of the brain. These nerves react immediately upon stimulation. For example, a person moves his hand as a reflex when he touches a hot object.
Structure and function of the peripheral nervous system
As mentioned above, a common function is to send information to the CZS and return to perform normal bodily functions. This helps regulate many functions, including fight or flight mechanisms, voluntary and involuntary actions. It also keeps inflammation under control and prepares the body for emergency situations.
1. crase number
As in the conflict above, there are 12 pairs of cranial nerves that enter and exit the skull. These 12 pairs are formed when motor, sensory, and mixed nerves come together. Some examples of cranial nerves are
- 7th Facial Nerve. the motor fibers of the 7th facial nerve support facial expressions, while the sensory fibers are responsible for transmitting information about taste.
- 5th Truncus. contains three components, as described below.
- Optic Nerve: the sensory nerve that nourishes the conjunctiva of the eye, forehead, skin and mucous membranes of the nose.
- Maxillaris: the emotional nerves, the lower eyelids, upper teeth and gum cheeks.
- Medibra: these are both motor and sensory nerves. This nerve assures the lower teeth, the gums and the mandible which helps to chew the jaw.
2. dorsal nerves.
31 pairs of dorsal spinal nerves exit and outward, widening the vertebral column. to periphery For many functions. Distribution of these nerves and functions is good.
- Cervical connections: this consists of 8 pairs. The nerves operate in the shoulder, neck, skin, etc. d. These nerves favor the reduction of the diaphragm.
- Shoulder connections: This consists of the first thoracic nerve and four cervical nerves. The nerves operate for the skin and fingertips of the neck.
- Thoracic nerve: This consists of 12 pairs. The nerves are operated by the muscles of the abdominal wall and chest.
- Lumbar connection: This consists of 5 pairs. The nerves are supplied subcutaneously, in the groin and thigh.
- Sacral connection: This consists of 5 pairs. Nerves are supplied to the hamstrings, knees, and lower extremities.
- Caudal plexus: is generated from one pair. The nerves go to the pelvis, anus (external sphincter), and external genital skin.
Peripheral Nervous System Diseases
Damage to peripheral nerves can cause peripheral Neuropathies can actually be classified as single root or multiple root disorders, depending on the extent and severity of nerve damage. One of the fairly common peripheral nerve injury disorders includes carpal tunnel syndrome, in which the nerves of the wrist and hand are damaged by overuse.
Mononeuropathy.
When only one peripheral Nerves are damaged. The condition is called mononeuropathy. It is due to nerve trauma or direct impact/compression of the nerves, which can cause nerve damage. People who lead sedentary lifestyles, such as those who use wheelchairs, are most likely to develop mononeuropathy.
Multiple Impairment.
When more than one nerve is damaged, it is referred to as multiple root damage. Multiple nerve injuries affect the body’s continuous functioning. Some of the cumulative causes of multiple symptoms are infiltration of the body via toxins released by pathogens, toxins produced by alcohol consumption, kidney damage, poor food, etc.
Peripheral nerve damage
As peripheral Nerves are not protected by membranes or rigid bone structures. They are more fragile and may just collapse. Because these nerves are directly connected to the spinal cord or brain, minimal damage to these nerves can still affect the central nerves. nervous system .
Symptoms of Peripheral Nervous System Problems
Common symptoms of peripheral Nerve damage can include numbness and tingling in muscles, especially in the arms and legs. Damage can also be the result of tragedy or injury. In this case, someone experiences a loss of emotion (perhaps as a result of nerve compression).
Treatment of Peripheral Nervous System Problems
Treatment depends on the underlying cause of the nerve injury. Following are some popular healing modalities
- If the damage is caused by diabetes, checking blood sugar levels may significantly reduce symptoms.
- Limit alcohol consumption so that poisons do not accumulate in the body.
- The use of anesthesia is effective in controlling the condition.
- In the case of muscular roles, somatic therapy is still recommended.
- If nerve damage affects blood circulation, a pacemaker is recommended with important criteria. system .
