INTRODUCTION : The glossopharyngeal nerve, known as the ninth cranial nerve (CN IX), is a mixed nerve that carries afferent sensory and efferent motor information. It exits the brainstem out from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve. Sensory: Innervates the oropharynx, carotid body and sinus,…
INTRODUCTION : The abducens nerve (or abducent nerve) is the sixth cranial nerve (CNVI), in humans body that controls the movement of the lateral rectus muscle, responsible for outward gaze. It is a somatic efferent nerve. ANATOMY OF ABDUCENS NERVE : The abducens nerve arises from the abducens nucleus in the pons of the brainstem….
INTRODUCTION: The frontalis muscle is a thin, wide, four-sided muscle located at the top front of the skull. The frontalis muscle only serves for facial expressions. It lifts the eyebrows while looking up thus creating a expression. ORIGIN: It originates from the Galea aponeutorica. INSERTION: This muscle has no bony attachments. The medial fibers continues…
Introduction of Olfactory Nerve : The olfactory nerve (CN I) is the first and shortest cranial nerve. It is a special visceral afferent nerve, which transmits information relating to smell. Embryologicallly, the olfactory nerve is derived from the olfactory placode (a thickening of the ectoderm layer), which also give rise to the glial cells which…
Introduction: The wrist extensor muscles of the hand are located in the back of the forearm and have long tendons connecting them to bones in the hand, where they exert their action. The wrist extensors includes extensor carpi radialis longus (ECRL), extensor carpi radialis brevis (ECRB), extensor digitorum (ED), extensor digiti minimi (EDM), extensor carpi…
Introduction The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves. Its name (“trigeminal” = tri-, or three, and – geminus, or twin: thrice-twinned) derives from the fact…
Introduction Neck muscles are bodies of tissue that produce motion in the neck when stimulated. The muscles of the neck run from the base of the skull to the upper back and work together to bend the head and assist in breathing. The neck muscles include Platysma, Sternocleidomastoid, Splenius capitis muscle, Longus capitis muscle, Longus…
Introduction The muscles that are involved in the act of gripping are known as Grip Muscles, the Grip Muscles are flexor digitorum profundus, flexor digitorum superficialis, flexor digiti minimi brevis, flexor pollicis longus, extensor digitorum, lumbricals, interossei, adductor pollicis. Anatomy of Grip Muscles 1. Flexor Digitorum Profundus Origin It originates from the upper 3/4 of…
Introduction The scapula provides attachment for several groups of muscles. scapular muscles include the supraspinatus, subscapularis, teres minor, infraspinatus, deltoid, and teres major. These muscles attach to the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint. Anatomy of scapular muscles 1. Supraspinatus Origin It originates from the medial…
Introduction to Elbow Flexors The flexor group – including the brachialis, biceps brachii, and brachioradialis bend the arm by decreasing the angle between the forearm and upper arm. The brachialis is the primary flexor of the elbow and is found mainly in the upper arm between the humerus and the ulna. Superficial to the brachialis…
