Dermatomes: What are they? Dermatomes are skin sites that receive sensory information from the Afferent nerve fibers that emerge from a certain spinal nerve root’s dorsal root. An external portion of a nerve that “communicates” with the spinal cord is known as a vertebral nerve root. The entire spinal cord is made up of nerve roots…
Neurotmesis is a type of severe peripheral nerve injury that results from nerve transection. Neurotmesis involves cutting off the entire nerve, affecting the endoneurium, perineurium, and epineurium. The myelin sheath, connective tissues, and axon are ruptured as a result of neurotmesis. When a peripheral nerve injury is severe enough to cause neurotmesis, the affected person as…
What is an Axonotmesis? The term “axonotmesis” describes the anatomical disruption of an axon that does not, or only partially, disturb the framework of connective tissue. Axonotmesis is a condition in which a peripheral nerve in one of the body’s limbs is injured. This type of injury results in damage to the axons and their…
Genitofemoral neuralgia is a chronic condition that affects the genitofemoral nerve, characterized by sharp, burning, or aching pain in these areas, often triggered by movements, pressure, or prolonged sitting. The genitofemoral nerve can become irritated or compressed due to various factors, including surgery, trauma, or certain medical conditions. Diagnosis can be challenging due to the…
Vagus nerve dysfunction may result from the vagus nerve’s inability to properly regulate several physiological functions. The vagus nerves transmit signals to your heart, brain, and digestive system. Your parasympathetic nervous system depends on it. Food not passing through your intestines, or gastroparesis can be caused by vagus nerve damage. Some people with vasovagal syncope faint because of…
Hypoglossal nerve palsy or paralysis is an occasional but clinically serious disorder that results from affecting the hypoglossal nerve (cranial nerve XII). The tongue’s intrinsic and extrinsic muscles, which are mostly supplied by this nerve, are essential for speaking, swallowing, and keeping the airway’s purity. These abilities can be severely impaired by damage to the hypoglossal nerve….
Introduction First of all, the human body parts are incredibly amazing. Every one of the numerous parts that comprise the human body serves a particular function. We carry out all tasks with our bodies. Let us educate you with the many names for our body parts. Body parts are the different sections of an individual…
Spinal Accessory Nerve Palsy, also known as Accessory Nerve Palsy, is a neurological condition characterized by the dysfunction of the spinal accessory nerve (cranial nerve XI). This nerve is primarily responsible for innervating the sternocleidomastoid and trapezius muscles, which are essential for head rotation, shoulder elevation, and certain movements of the neck and scapula. Damage…
Introduction The hypoglossal nerve is the 12th paired cranial nerve. Its name is derived from ancient Greek, where ‘hypo’ means under and ‘glossal’ means tongue. Except for the palatoglossus, which is innervated by the vagus nerve, the nerve has a solely somatic motor function, innervating the intrinsic and extrinsic muscles of the tongue. The hypoglossal…
Abducens nerve palsy is a disorder where injury to a specific nerve disrupts eye movement and alignment. The abducens nerve, one of the pairs of cranial nerves, regulates the movement of your eyes away from your nose. Abducens nerve palsy is a nerve problem that involves eye muscle control. It makes turning an affected eye…
