Nerves along the cord consists of: 8 cervical nerves (C1 - C8) 12 thoracic nerves (T1 - … The spinal cord can be divided into segments according to the nerve roots that branch off of it. request uri=/nerve-chart-nerve-roots-innervation-symptoms/ spinal nerve via hypoglossal nerve Sternohyoid 31 manubrium & medial end of clavicle lower margin of hyoid bone • depresses larynx & hyoid bone if mandible is fixed • may also flex skull Cervical spinal nerves 1-3 Sternothyroid 32 posterior surface of manubrium thyroid cartilage • pulls thyroid cartilage (plus larynx & hyoid) inferiorly Dec 18, 2018 · Muscle Weakness. The C4 and C5 nerves supply motor function to the muscles of the shoulder and arm. When either of these nerves is compromised, muscle weakness can result. Specifically, the C4 nerve enervates the levator scapulae, trapezius and rhomboid muscles. Damage to the C4 nerve may result in difficulty in elevating the shoulders. chart of effects of spinal misalignments “The nervous system controls and coordinates all organs and structures of the human body.” (Gray’s Anatomy, 29 th Ed., page 4). Misalignments of spinal vertebrae and discs may cause irritation to the nervous system and affect the structures, organs, and spinal nerve via hypoglossal nerve Sternohyoid 31 manubrium & medial end of clavicle lower margin of hyoid bone • depresses larynx & hyoid bone if mandible is fixed • may also flex skull Cervical spinal nerves 1-3 Sternothyroid 32 posterior surface of manubrium thyroid cartilage • pulls thyroid cartilage (plus larynx & hyoid) inferiorly There are around 640 skeletal muscles within the typical human body. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented in this article. These muscles have a common embryonic origin – the 2nd pharyngeal arch. They migrate from the arch, taking their nerve supply with them. As such, all the muscles of facial expression are innervated by the facial nerve. The facial muscles can broadly be split into three groups; orbital, nasal and oral. Jul 12, 2015 · All this is happening at the microscopic level, mind you, but depending on the size of the muscle and the jobs it does, a nerve cell can innervate as few as six to 10 muscle cells (think fingers that play piano, chop vegetables, sew, write, or muscles around the eye's that help focus, blink away tears, keep you safe on the road, and more) to hundreds (think mid-back and arm muscles, where fine ...

All of these nerves extend as branches of nerves in the leg that pass through the ankle and into the foot. The sural nerve branches from the tibial and common fibular nerves and is responsible for feeling on the outside of the foot and the small toe.

The extraocular muscles develop along with Tenon's capsule (part of the ligaments) and the fatty tissue of the eye socket (orbit). There are three centers of growth that are important in the development of the eye, and each is associated with a nerve. Hence the subsequent nerve supply (innervation) of the eye muscles is from three cranial ...

VERTEBRAL SUBLUXATION AND NERVE CHART "The nervous system controls and coordinates all organs and structures of the human body." (Gray's Anatomy, 29th Ed., page 4) Misalignment of spinal vertebrae and discs may cause irritation to the nervous The nerve supplying a muscle is called motor nerve. In fact it is a mixed nerve and consists of the following types of fibers. Motor fibers: These fibers make up to 60% of a nerve to skeletal muscle. They comprise of: Large myelinated alpha efferents which supply extrafusal muscle fibers. pronator quadratus is the deepest muscle in the distal forearm; it works with pronator teres and has the same nerve supply: pronator teres: common flexor tendon and (deep or ulnar head) from medial side of coronoid process of the ulna: midpoint of the lateral side of the shaft of the radius: pronates the forearm: median nerve Latissimus Dorsi muscle: Radial Nerve: Brachial Plexus: Posterior Cord (C5-C8, T1) Posterior Brachial and Antebrachial Cutaneous Nerves; Deep Branch; Superficial Branch: Radial groove of mid-humerus; deep to Triangular Interval; in the Anatomical Snuffbox; Gives off posterior brachial and antebrachial cutaneous nerves: POSTERIOR ARM, POSTERIOR FOREARM A second intercostobrachial nerve is frequently given off from the lateral cutaneous branch of the third intercostal; it supplies filaments to the axilla and medial side of the arm. FIG. 821– Intercostal nerves, the superficial muscles having been removed. (Testut). The Lower Thoracic Nerves. The extraocular muscles develop along with Tenon's capsule (part of the ligaments) and the fatty tissue of the eye socket (orbit). There are three centers of growth that are important in the development of the eye, and each is associated with a nerve. Hence the subsequent nerve supply (innervation) of the eye muscles is from three cranial ... The nerve passes through the pyramidal eminence to supply the stapedius muscle in the middle ear. Between the stylomastoid foramen, and the parotid gland, three more motor branches are given off: Posterior auricular nerve – Ascends in front of the mastoid process, and innervates the intrinsic and extrinsic muscles of the outer ear. Page 4 Note: Neurological innervation of the spinal nerves of the human body overlap in its supply to different areas and parts of the body as well as differ somewhat in different persons. This chart is a simplification of actual innervation.
