The serratus ventralis muscle is a large fleshy muscle placed on the lateral side of the neck and thorax and is named as serratus thoracis and serratus cervicis according to the region covered. Serratus cervicis It is a large, thick muscle extends from the level of the second cervical vertebra to the fifth rib. The posterior […]
Latissimus dorsi muscle is a very wide muscle extending on the lateral wall of the thorax from the dorso-lumbar spine to the arm. It has an aponeurotic origin, which is succeeded by a wide muscular portion. Origin: Lumbodorsal fascia, 11 th and 12 th ribs and fascia over the intercostal and external oblique muscles. Insertion: The anterior
Omotransversarius muscle muscle extends from the level of the atlas to the shoulder and most part covered by the preceding muscle except at the scapular portion where it is seen as a broad
Branchiocephalicus Muscle muscle extends from the head, along the neck to the arm. Its upper border is in close apposition with the trapezius and the lower border forms the upper boundary of the jugular furrow. It consists of a dorsal part (cleido-occipitalis) and a ventral part (cleido-mastoideus), the division being indicated by the position of exit
Trapezius Muscle is a broad triangular muscle extending along the dorsal midline from the level of atlas to the end of the thoracic region, and covers a part of the shoulder. It consists of cervical (trapezius cervicis) and dorsal(trapezus thoracis) parts. Origin: Ligamentum nuchae and supraspinous ligament from the level of the atlas to the twelfth dorsal vertebra. Insertion: The tuberous part
Axilla It is a narrow space between the chest wall and the pectoral limb containing a large amount of loose connective tissue. This space is crossed by the large vessels and the nerves intended to supply the muscles of the pectoral limb. It corresponds to the armpit of the man. In resting condition, this space
The forelimb is attached to the body by a group of muscles called muscles of the shoulder girdle. These muscles connect the forelimb with the head, neck and trunk. They are as follows Pectoral Muscles Superficial pectoral Cranial superficial pectoral Caudal superficial pectoral Deep pectoral Trapezius Muscle Trapezius cervicis Trapezius thoracis Branchiocephalicus Muscle Omotransversarius muscle Latissimus dorsi muscle Serratus
Ox Musculus Cutaneous / Cutaneous muscle / Panniculus carnosus Some striated muscles are placed at the subcutis in some parts of the body are known as cutaneous muscles. In some places, these fibers are inserted into the skin. They may have connection with the skeleton. It is divided into – Facial (cutaneous facial) part Omo-brachial (cutaneous
The accessory structures of the muscles are the fasciae and synovial membranes. Synovial membranes are thin walled sacs.
Cardiac muscle is found only in the heart, the immediate proximal ends of aorta, pulmonary artery and pulmonary veins
