Musculocutaneous nerve & axillary nerve.output
The axillary nerve emerges from the posterior cord of the brachial plexus and passes through the quadrangular space in the axilla. It has both motor and sensory functions. The anterior terminal branch innervates the deltoid muscle, while the posterior terminal branch supplies the teres minor muscle and gives off the upper lateral cutaneous nerve, which provides sensation to the skin over the lower deltoid. Damage to the axillary nerve results in paralysis of the deltoid and teres minor muscles and loss of sensation in the regimental badge area.

There are two groups of muscles in the back of the forearm - a superficial group and a deep group. The superficial group contains 7 muscles that originate on the lateral epicondyle of the humerus and insert on the bones of the hand and fingers. They function to extend the wrist and fingers. The deep group contains 5 muscles that originate on the bones of the forearm and insert on the thumb and second finger. They function to supinate the forearm and extend the thumb.
Lumbosacral plexus by dr swapan (1)
The lumbosacral plexus is formed by the anterior rami of the L1-S3 nerve roots. It is divided into the lumbar plexus (L1-L4), lumbosacral trunk (L4-L5), and sacral plexus (S1-S4). The lumbar plexus forms branches including the femoral, obturator, lateral femoral cutaneous, and genitofemoral nerves. The sacral plexus forms the sciatic nerve and its tibial and common fibular divisions, as well as the superior and inferior gluteal and posterior cutaneous nerves of the thigh. Injuries and disorders like trauma, tumors, radiation, and diabetes can
Anatomy of Hand
The document provides an overview of the anatomy of the hand. It describes the 27 bones in the hand and wrist, including the carpals, metacarpals, and phalanges. It outlines the extrinsic muscles that flex and extend the wrist and digits, as well as the intrinsic muscles of the hand including the thenar, hypothenar, lumbricals, and interossei groups. It also briefly discusses the arterial and venous blood supply, as well as the innervation of the hand by the median and ulnar nerves.
Radial artery
The radial artery begins in the cubital fossa at the level of the radius neck. It passes downwards and laterally beneath the brachioradialis muscle, resting on the deep forearm muscles. In the middle third, the radial nerve lies laterally. The radial artery leaves the forearm by winding around the lateral wrist aspect and reaches the posterior hand beneath tendons. It descends on the dorsum beneath muscles before turning forward into the palm, where it forms the deep palmar arch. The radial artery gives off several branches in the forearm and hand and anastomoses with other arteries. Clinically, the radial pulse is used to measure blood pressure and the artery can be used for coronary bypass
Anatomy of flexor compartment of forearm
The median nerve passes between the two heads of the pronator teres muscle. The ulnar nerve passes between the two heads of the flexor carpi ulnaris muscle. Injuries to these nerves can result in characteristic hand deformities - injury to the median nerve can cause an "ape hand" and injury to the ulnar nerve can cause a "claw hand". The anterior and posterior interosseous nerves branch from these main nerves and supply muscles in the forearm but do not reach the skin.
Nerve anatomy
This document provides an overview of peripheral nerve anatomy, focusing on the radial, median, and ulnar nerves. It describes the origin, course, branches, and innervation of each nerve. The radial nerve originates from the brachial plexus and provides motor innervation to muscles of the posterior arm and forearm. The median nerve originates in the axilla from the brachial plexus and provides motor innervation to muscles of the anterior forearm and hand. The ulnar nerve originates from the medial cord of the brachial plexus and provides motor innervation to muscles of the medial forearm, hand, and fingers.
Palmar arterial arches
The superficial palmar arch is the dominant vascular structure of the palm. It is formed by the anastomoses of the superficial branch of the ulnar artery and the superficial palmar branch of the radial artery. It gives off four palmar digital arteries that supply the medial 3.5 fingers. The deep palmar arch lies deep to the superficial arch and connects the ulnar and radial arteries, supplying the medial four metacarpals. Variations can occur in the formation of the superficial palmar arch, which is important to identify during hand surgery.

It describes the origin, course, branches, and innervation of each nerve. Key points include that the brachial plexus provides cutaneous and motor innervation to the upper limb and gives rise to the five main nerves. Injuries to specific nerves can result in characteristic muscle weakness or sensory loss depending on the innervation.
Cervical
The cervical spine consists of several joints including the atlanto-occipital joint and the atlanto-axial joint. It provides mobility but sacrifices stability, making it vulnerable to injury. The cervical spine can flex and extend between 15-20 degrees, side bend about 10 degrees, and rotate 50 degrees at the atlanto-axial joint. It is stabilized by muscles like the sternocleidomastoid and ligaments such as the transverse ligament of the atlas. Injuries can cause neck pain and symptoms extending into the head, arms, and shoulders.

Surgical approaches that put certain nerves at risk are mentioned. The document aims to provide an overview of the key anatomy and clinical considerations regarding nerves of the brachial plexus and upper limb.
Radial nerve
The radial nerve arises from the posterior cord of the brachial plexus and supplies motor innervation to the posterior compartment muscles of the arm and forearm. It has both motor and sensory branches. In the arm, it gives off branches that innervate the triceps and passes through the spiral groove between the humerus and triceps. In the forearm, it divides into a deep motor branch and superficial sensory branch. Damage to the radial nerve can occur at different locations like the axilla, spiral groove, or radial tunnel at the elbow, resulting in characteristic motor and sensory deficits depending on the site of injury.
Brachial Plexus Anatomy
The brachial plexus is a network of nerves formed by the lower cervical and upper thoracic spinal nerves that provides motor innervation to the muscles of the upper limb and sensory innervation to the skin of the upper limb. It is divided into 5 parts - roots, trunks, divisions, cords, and branches.

Spinal Nerves in Nervous System in Physiology
Spinal nerves originate from the spinal cord and carry sensory and motor information between the brain and body. There are 31 pairs of spinal nerves that are named according to the region of the spinal cord they emerge from. Each spinal nerve divides into branches that innervate specific regions of the body and control associated muscles and skin areas. Damage to spinal nerves can occur through conditions like herniated discs, trauma, infections, and compressive neuropathies, leading to issues such as pain, weakness, and numbness.

The document discusses the structure and organization of the nervous system. It describes the central nervous system as comprising the brain and spinal cord. The brain is divided into the cerebrum, cerebellum and brainstem. The spinal cord contains gray matter surrounded by white matter and extends from the brainstem down the back. The peripheral nervous system includes cranial nerves, spinal nerves and plexuses. The somatic nervous system innervates skeletal muscles and carries sensory information from the skin. The autonomic nervous system regulates involuntary functions and is divided into the sympathetic and parasympathetic systems.
Spinal Nerve
Spinal nerves emerge from the spinal cord and carry sensory and motor information between the spinal cord and specific body regions. There are 31 pairs of spinal nerves that are categorized based on the region of the spinal cord they emerge from. The anterior rami of spinal nerves form plexuses that further distribute nerves to various body structures, while the thoracic spinal nerves directly innervate the intercostal muscles and skin as intercostal nerves.
Anatomy Of NECK.pptx
The neck contains many vital structures and connects the head to the torso. The skeleton of the neck includes 7 cervical vertebrae, the hyoid bone, manubrium, and clavicles. The neck separates into anterior and posterior triangles divided by the sternocleidomastoid muscle. The triangles contain muscles, vessels, and nerves. Conditions like torticollis can cause neck twisting that is treated with physiotherapy including massage, stretches, and exercises to improve range of motion.
Ans changed
The peripheral nervous system consists of the spinal nerves, cranial nerves, autonomic nervous system, and peripheral nerve fibers. The autonomic nervous system is further divided into the sympathetic and parasympathetic nervous systems which generally have opposing effects on target organs. The sympathetic nervous system is responsible for the "fight or flight" response and mobilizes the body during stress through thoracolumbar outflow. The parasympathetic nervous system is responsible for "rest and digest" functions through craniosacral outflow.
Trigeminal nerve and its applied anatomy
The trigeminal nerve is the largest of the cranial nerves and provides sensory and motor innervation to the face. It has three major branches - the ophthalmic, maxillary, and mandibular nerves. The ophthalmic nerve further divides into the frontal, lacrimal, and nasociliary nerves. The nasociliary nerve branches into the anterior and posterior ethmoidal nerves which supply sensory innervation to the paranasal sinuses and nasal cavity.

There are 31 pairs of spinal nerves that emerge from the spinal cord and transmit signals between the spinal cord and specific body regions. They are divided into cervical, thoracic, lumbar, sacral, and coccygeal nerves. The anterior rami of spinal nerves form plexuses that branch into major nerves like the brachial plexus and lumbar plexus, which provide motor and sensory innervation to the limbs and trunk. Intercostal nerves also directly innervate the chest wall.
