rectus femoris
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
The gracilis crosses both the hip joint and the knee joint. It originates from the pubic bone and inserts onto the tibia.
The only muscle capable of flexing the distal interphalangeal joints is the flexor digitorum profundus. This muscle originates from the ulna and interosseous membrane in the forearm and inserts on the distal phalanges of the fingers. It is responsible for flexing the distal interphalangeal joints while the flexor digitorum superficialis flexes the proximal interphalangeal joints.
superior extensor retinaculum and inferior extensor retinaculum
The gastrocnemius muscle crosses the joint posteriorly. It originates from the posterior aspect of the femur and inserts into the calcaneus via the Achilles tendon.
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
The semimebranosus is part of the hamstring group and originates at the ischial tuberosity and inserts into the proximal tibia.
The piriformis originates at the anterior sacrum and inserts at the greater trochanter of the femur.
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
Origin: the gluteus maximus originates from the posterior inferior surface of the sacrum and coccyx, and the posterior medial surface of the ilium.Insertion: the gluteus maximus inserts into the gluteal tuberosity on the posterior aspect of the femur, and the anterior aspect of the lateral tibial condyle.
The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
In human anatomy, the tibialis anterior is a muscle that originates in the upper two-thirds of the lateral surface of the tibia and inserts into the medial cuneiform and first metatarsal bones of the foot. Its acts to dorsiflex and invert the foot.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
The primary muscle responsible for moving the scapula forward and downward is the serratus anterior. This muscle originates along the upper eight or nine ribs and inserts along the inner border of the scapula. Contraction of the serratus anterior pulls the scapula forward and downward along the ribcage.
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
