Triceps muscle, any muscle with three heads, or points of origin, particularly the large extensor along the back of the upper arm in humans. It originates just below the socket of the scapula (shoulder blade) and at two distinct areas of the humerus, the bone of the upper arm. It extends downward. Total of 4,777 number cases were reviewed, 5 cases were identified to have injury of triceps brachii tendon. Four out of 5 cases were Pomeranians, and the other one is Shetland sheepdog. The odds ratio of Pomeranians was 122.5 (95% CI: 13.6−1102.2). For a case of Shetland sheepdog which had severe tendon injury with bone fragment due to The latissimus dorsi is a broad, flat muscle occupying most of the lower posterior thorax. The muscle's primary function is to move the upper extremity, but it is also considered an accessory muscle of respiration. Due to this muscle's broad attachment to several vertebral spinous processes and the thoracolumbar fascia, ongoing research looks at what role the muscle plays in trunk movement The primary function of the triceps is the extension of the elbow joint. It is composed of three heads (tri = three, cep = head): a long head, a lateral head, and a medial head. The tendons all have different origins, but the three heads combine to form a single tendon distally. Important Functions. The long head of the triceps does some pretty cool things that make it stand out from its tricep siblings. Double the arm action: This part of the muscle helps you straighten and bring down your arm. Arm-controller: The long head is super useful for steadying your arm in certain positions. Thank you for the balance! The biceps and triceps act against one another to bend and straighten the elbow joint. To bend the elbow, the biceps contracts and the triceps relaxes. smooth muscle fibers do contract together, causing the muscle to shorten. Smooth muscles have numerous functions, including the following. The smooth muscle in the uterus helps a woman to The main function of the triceps surae is to plantar flex the foot. In addition, the gastrocnemius portion of the muscle aids the flexion of the leg, while the soleus assists in maintaining the steady posture while standing on the ground. This article will discuss the anatomy and function of the triceps surae muscle. Identify the movement and function of the pectoral girdle and upper limbs; The forearm flexors include the biceps brachii, brachialis, and brachioradialis. The extensors are the triceps brachii and anconeus. The pronators are the pronator teres and the pronator quadratus, and the supinator is the only one that turns the forearm anteriorly The triceps, or triceps brachii, is Latin for the three-head muscle of the arm made up of three separate muscles — long, medial, and lateral head — with different origins, but they all converge in the same place on the elbow. The triceps long head is the biggest of the three muscles and originates at the infraglenoid tubercle of the scapula. Triceps. The three-headed triceps muscle is the only muscle in the back of the arm. The triceps provides the important action of straightening our elbow, allowing us to push up out of a chair and throw a ball. It functions as a flexor of the wrist, and like the FCR is expendable. In fact, it is absent in one or both arms in 12%-25% of JWe4gib.
