Complex muscle This is a single muscle situated on the dorso-lateral aspect of the leg. Origin: By a strong tendon from the extensor fossa of the femur. This shows about its middle three muscular bellies, each of which is succeeded by a tendon. The peroneus tertius is the most superficial part and well developed. It is located […]
Fascia The fascia of the leg consists of several super-imposed layers. The superficial fascia is continuous with that of the thigh. The tendons of the tensor fascia latae, biceps femoris, semitendinosus, gracilis and sartorius formthe next layer. These two layers frequently use together and are attached to the patellar ligaments, tibial crest and medial face
The following are the muscles present on the anterior aspect of the thigh. Sartorius (Already described in medial group of muscles of thigh) Quadriceps femoris Rectus femoris Vastus lateralis Vastus medialis Articularis genu Quadriceps femoris This is a massive muscle composed of four divisions situated around the anterior, lateral and medial faces of the femur. Of these
This region has eight muscles arranged in superimposed layers. They are First layer Sartorius Gracilis Second layer Pectineus, Adductor and Semimembranosus Third layer Quadratus femoris, Obturator internus, Obturator externus and Gemellus Of these the obturator internus is placed within the pelvic cavity. FIRST LAYER Sartorius This is a long, thin and flat muscle and is the anterior
The lateral aspect of the hip and thigh muscles are as follows – Tensor fasciae latae (Tensor vaginae femoris) Biceps femoris Gluteus medius (Middle gluteus) Gluteus profundus (Deep gluteus) Semitendinosus Tensor fasciae latae (Tensor vaginae femoris) This is the anterior most muscle on the external aspect of the hip and thigh. It is triangular in form with its base below
Lateral muscles of Hip and Thigh Tensor fasciae latae (Tensor vaginae femoris) Biceps femoris Gluteus medius (Middle gluteus) Gluteus profundus (Deep gluteus) Semitendinosus Medial muscles of Hip and Thigh First layer Sartorius Gracilis Second layer Pectineus, Adductor and Semimembranosus Third layer Quadratus femoris, Obturator internus, Obturator externus and Gemellus Anterior Muscles of Thigh Sartorius Quadriceps femoris Rectus femoris
Fascia of Thigh The superficial fascia of the thigh does not merit any special description. The internal portion of the deep fascia covers the first layer of the muscles on the inner aspect of the thigh and becomes continuous inferiorly with the fascia of the leg and interiorly with that part of the deep fascia,
The variations in the musculature of the dog is given below. The posterior superficial pectoral is thin and narrow. The anterior deep pectoral is feeble and terminates along with the posterior deep pectoral on the humerus. The trapezius is thin and divided into cervical and dorsal portions. The right and left muscles meet on a fibrous raphe. The omotransversarius is a well developed
The variations in the musculature of the horse is given below. The anterior superficial pectoral is more distinct than the posterior. The deep pectoral is divisible into anterior and posterior divisions. The anterior deep pectoral extends in front of the supraspinatus to the cervical angle of the scapula. The posterior is fan shaped. The trapezius
Flexor muscle of Arm region muscles are situated around the posterior and medial aspects of the forearm. They are arranged in two layers – superficial and deep. Superficial layer Pronator teres Flexor carpi radialis (Medial flexor of the carpus) Flexor carpi ulnaris (Middle flexor of the carpus) Ulnaris lateralis (Flexor metacarpi externus) Deep layer Superficial digital flexor (Flexor pedis
