Attachments: Originates from the ulna and associated interosseous membrane. At the wrist, it splits into four tendons. These pass through the carpal tunnel and attach to the base of the distal phalanx of the each digit.

Actions: Flexion at the distal interphalangeal joint of the digits. It also performs flexion at the wrist, metacarpophalangeal and proximal interphalangeal joints.

Attachments: Originates from the tubercle of the trapezium and from the associated flexor retinaculum. Attaches to the base of the proximal phalanx of the thumb.

Actions: Flexes the metacarpophalangeal joint of the thumb.

Attachments: Originates from the lateral epicondyle of the humerus. The tendon divides into four in the distal forearm, and inserts into the extensor hood of each digit.

Actions: Extension of the digits at the interphalangeal and metacarpophalangeal joints.

Attachments: Originates from the medial and lateral surfaces of the humerus shaft. It inserts onto the ulnar tuberosity, immediately distal to the elbow joint.

Function: Flexion at the elbow.

Attachments: 

1. Originates from the medial epicondyle of the humerus and the olecranon of the ulna.

2. Attaches to the pisiform bone, hook of hamate, and base of the 5th metacarpal.

Actions: Flexion and adduction at the wrist.

Attachments: Originates from the lateral epicondyle of the humerus and attaches to the base of the 5th metacarpal .

Actions: Extension and adduction of wrist.

Attachments: Originates from the intertrochanteric line and medial lip of the linea aspera of the femur. It inserts onto the patella via the quadriceps femoris tendon. The patella is then attached to the tibial tuberosity by the patella ligament.

Actions: Extension of the knee joint. It has a secondary function of stabilising the patella.

Attachments: Originates from the ischial tuberosity (more superiorly than the origin of the semitendinosus and biceps femoris). Attaches to the medial tibial condyle.

Actions: Flexion of the leg at the knee joint. Extension of thigh at the hip. Medially rotates the thigh at the hip joint

Attachments: Originates from the soleal line of the tibia and proximal fibula. The muscle converges with the fibres of the gastrocnemius to form the calcaneal tendon, which inserts onto the calcaneus.

Actions: Plantarflexion of the foot at the ankle joint
