What is the sacral plexus? The sacral plexus is placed on the posterolateral wall of the pelvic cavity, fibbing anterior to the Piriformis. The sacral subsidies part out of the anterior sacral foramina and course laterally & inferiorly on the pelvic wall. A majority of the nerves originating from the sacral plexus pass through the…
What is lumbar plexus? The lumbar plexus is a vital collection of nerves that arise from mostly the lumbar medulla spinalis. The term plexus refers to a “web” of nerves that’s created just lateral to where T12-L5 exit the neural structure via intervertebral foramina. The plexus exists bilaterally and allows nerves to mix with different…
What is Ulnar Nerve? The ulnar nerve arises from C8-T1 nerve roots which form the medial cord of the brachial plexus. The cubital nerve travels down the hand where it moves behind the medial epicondyle of the humerus at the elbow. The nervous doesn’t give branches within the axilla or within the upper arm. It…
What is Radial Nerve? The Radial nerve is one in all the terminal branches of the posterior cord. within the axilla, it lies behind the axillary and upper brachial arteries and passes anterior to the tendons of the teres muscle, latissimus dorsi, and subscapularis. It arrives in the posterior compartment of the arm transient via…
What is a Musculocutaneous Nerve? The brachial plexus is the complex set of nerves originating from the ventral roots of C5-T1 that innervates numerous muscles and cutaneous regions of the upper limb, thorax, and back. The 5 spinal roots form a superior, middle, and inferior trunk. Each of those trunks has an anterior and posterior…
What is Axillary Nerve? The axillary nerve is one of the terminal branches brachial plexus, derived from its posterior cord (C5-6). It travels through the quadrangular space along with the posterior arterial blood vessel and vein. It is a mixed nerve, meaning that it’s both motor and sensory fibers that innervate important muscles of the…
What is Brachial Plexus? The Brachial Plexus could be a network of nerves that offers rise to all or any of the motor and sensory nerves of the upper extremity. It rises from the anterior rami of spinal nerves C5-T1 that sustain various combinations and splits into trunks and divisions until they finally create their…
What is Myotonic Muscular Dystrophy? Myotonic dystrophy is an inherited sort of genetic disease that affects the muscles and other body systems. folks that have Steinert’s disease have muscle wasting and weakness in their lower legs, hands, neck, and face that exasperate over time. Signs and symptoms of dystrophy usually develop when someone is in…
What is Oculopharyngeal Muscular Dystrophy? Oculopharyngeal genetic disorder (OPMD) could be a rare kind of genetic disease with symptoms generally starting when a person is 40 to 50 years old. It is often autosomal dominant neuromuscular disease or autosomal recessive. the foremost common inheritance of OPMD is autosomal dominant, which implies just one copy of…
What is Emery-Dreifuss Muscular Dystrophy? Emery-Dreifuss muscular dystrophy may be a condition that primarily affects muscles used for movement (skeletal muscles) and also the heart (cardiac muscle). Among the earliest features of this disease are joint abnormalities called contractures. Contractures restrain the movement of certain joints, most frequently the elbows, ankles, and neck, and frequently…
