The gastrointestinal tract (GI tract) has a complex control mechanism that relies on coordinated interaction between muscular contractions and neuronal impulses (nerve signals). [3] Fecal incontinence or constipation occurs when there is a problem with normal bowel functioning. This could be for a variety of reasons.
Anterior cutaneous nerve entrapment syndrome (ACNES) is a nerve entrapment condition that causes chronic pain of the abdominal wall. [1] It occurs when nerve endings of the lower thoracic intercostal nerves (7–12) are 'entrapped' in abdominal muscles, causing a severe localized nerve (neuropathic) pain that is usually experienced at the front of the abdomen.
The diagnosis of enteric neuropathy is rather difficult, in that many symptoms present in ways that are common to many other bowel-and gut-related diseases. It is common that many people undergo many surgeries, sometimes over several years, to attempt to combat other possible diseases. The diagnosis itself is conducted by a physician based on ...
Pudendal nerve entrapment (PNE) is an uncommon, chronic pelvic pain condition in which the pudendal nerve (located in the pelvis) is entrapped and compressed. There are several different anatomic locations of potential entrapment (see Anatomy). Pudendal nerve entrapment is an example of nerve compression syndrome.
Cauda equina syndrome (CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged. [2] Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. [1]
The pudendal nerve is the main nerve of the perineum. [1]: 274 It is a mixed (motor and sensory) nerve and also conveys sympathetic autonomic fibers.It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.
Studies have shown overlapping mechanisms in psoriasis and depression; psoriasis causing disturbances in the gut microbiota that reflect in the brain causing depression that in turn can cause the stress that affects the microbiome. [39] Probiotics may reduce symptoms of depression through the vagus nerve and sympathetic pathways.
The inferior rectal nerves (inferior anal nerves, inferior hemorrhoidal nerve) usually branch from the pudendal nerve but occasionally arises directly from the sacral plexus; they cross the ischiorectal fossa along with the inferior rectal artery and veins, toward the anal canal and the lower end of the rectum, and is distributed to the sphincter ani externus (external anal sphincter, EAS) and ...
