What is the Perineal Nerve? The perineal nerve is a branch of the pudendal nerve and serves the external genitalia of both sexes as well as the perineal area, which is the space between the scrotum and the anus in men, and between the vagina and the anus in women.amage to the perineal nerve may cause decreased sexual sensation. Problems with the perineal nerve may cause incontinence in people of all ages, including the elderly. In women, the perineum is located between the anus and vagina.

Median nerve The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, and has contributions from ventral roots of C5 & C6 (lateral cord) and C8 & T1 (medial cord). The median nerve is the only nerve that passes through the carpal tunnel.

The Structure and Function of the Digestive System The anus is the last part of the digestive tract. It consists of the pelvic floor muscles and the two anal sphincters (internal and external muscles). The lining of the upper anus is specialized to detect rectal contents.

- Cranial Nerves. There are 12 pairs of cranial nerves and because they are nerves, they are considered to be a part of the peripheral nervous system (PNS). Conventionally, each of the 12 pairs of nerves is named using a Roman numeral (I through XII) together with the descriptive name for the nerve.-Olfactory Nerve. is a sensory nerve (a nerve carrying sensation information to the brain) that arises in the nasal mucosa (up through the olfactory foramina of the cribriform plate) and conveys impulses for the sense of smell to the brain.

Pudendal Neuralgia The pudendal nerve is the main nerve of the perineum. The perineum is the area between the testicles and anus of a man, and the vagina and anus of a woman. When this nerve suffers an injury, it can result in the most chronic and disabling form of pelvic pain, pudendal neuralgia.[1].

- In females, ischiocavernosus has a similar origin but it inserts into the crura of the clitoris. Its function is similar: to retard venous return so erecting the clitoris.

- Bumhole redirects here. It is not to be confused with Bunghole. The human anus (from Latin anus meaning ring, circle) is the external opening of the rectum. Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus.

- Im replacing my underground electrical conduit to my well with gray electrical PVC. This is a 20 foot run 40 inches below grade. The pipe will contain three 12 AWG wires to the pump. This pipe run is basically under a flower bed in the front of the house and is not subject to physical damage. Im planning to use 1 1/4 inch Schedule 40 PVC but am starting to think why not use Schedule 80.

Facial Nerve Disorders Each of the two facial nerves not only carries nerve impulses to the muscles of one side of the face, but also carries nerve impulses to the tear glands, saliva glands, to the muscle of a small middle ear bone (the stapes) and transmits taste fibers from the front of the tongue and pain fibers from the ear canal.

Abducens nerve From Wikipedia, the free encyclopedia. The abducens nerve or abducent nerve (the sixth cranial nerve, also called the sixth nerve or simply CNVI) is a somatic efferent nerve that, in humans, controls the movement of a single muscle, the lateral rectus muscle of the eye.he abducens nerve leaves the brainstem at the junction of the pons and the medulla, medial to the facial nerve. In order to reach the eye, it runs upward (superiorly) and then bends forward (anteriorly). The nerve enters the subarachnoid space when it emerges from the brainstem.

- Sacral Nerves. The brain tells the bladder and bowel what to do by sending electrical signals to the muscles in the pelvic floor, the sphincters, the urethra as well as the bladder and rectal area. The messages or impulses sent by the brain to the pelvic area are carried by a system of special fibres called nerves.

Obturator nerve Obturator nerve. The obturator nerve begins at the medial border of the psoas major muscle. It travels through the obturator foramen (an opening in the pelvic bone) before entering the thigh, where it branches into two parts, an anterior branch and posterior branch.

- For the comedy-drama film, see Funny Bones. For the comedy club, see The Funny Bone. In human anatomy, the ulnar nerve is a nerve that runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest unprotected nerve in the human body (meaning unprotected by muscle or bone), so injury is common.

Hemorrhoids Hemorrhoids are venous cushions. They are a part of our anatomy just like our eyes, nose, ears, toes, etc. We are born with at least 6 hemorrhoids, three within the anus (internal hemorrhoids) and three outside the anal opening (external hemorrhoids). External hemorrhoids are abundant in nerve endings.

- These nerves all pass through the superior orbital fissure, a foramen in the sphenoid bone at the rear of the eye socket. Cranial nerve 3, the oculomotor nerve, is a motor nerve that controls muscles around the eye, as well as the ability of the pupil to respond to light changes.ranial nerve 6, the abducent nerve, is a motor nerve that allows the eye to move laterally. Cranial Nerve 5, Maxillary Branch. The maxillary branch of the trigeminal nerve, a sensory branch that supplies the upper lip, sinuses and palate, passes through the foramen rotundum, an opening in the middle of the skull.

- Two important sacral nerves to the functioning of the bladder and bowel are the pudendal nerve and the pelvic splanchnic nerve. Through a series of reflexes and signals the nerves and the bladder and bowel coordinate with the pelvic floor muscles and external urinary and anal sphincters.

- Pudendal neuralgia is a rare problem with the pudendal nerve that can affect both men and women. The pudendal nerve runs through your pelvic region, including your genitals, urethra, anus, and perineum.Your perineum is the area between your anus and genitals.en with pudendal neuralgia may have pain in the buttocks, scrotum, penis, and perineum. Women with pudendal neuralgia may have pain in their buttocks, vulva, urethra, and perineum. For more information, talk to your doctor.

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality If you recall, CN VII is responsible for taste sensation in the anterior two-thirds of the tongue. Well, it's the glossopharyngeal nerve, also known as cranial nerve IX, that is the nerve responsible for the sensation of taste in the posterior one-third of the tongue. In addition, cranial nerve IX is a nerve that innervates one of the three major salivary glands, called the parotid gland.

Olfactory nerves Olfactory nerves. Also known as CN1, the olfactory nerve is the first of 12 cranial nerves located within the head. It relays sensory data to the brain, and it is responsible for the sense of smell. The nerve's olfactory receptors are located within the mucosa of the nasal cavity.Unlike many other nerves, CN1 does not possess two trunks. Rather, its sensory fibers extend through the ethmoid bone's cribriform plate, a part of the skull located behind the nose.Once airborne chemicals and particles enter the nasal cavity, they interact with these neural receptors.nlike many other nerves, CN1 does not possess two trunks.
