what is the origin and insertion of flexor hallucis longus?
449240
Flexor hallucis longus arises from the posterior two thirds of the fibula and descends on the fibular side of the leg. It then crosses over the posterior part of the ankle to emerge on the sole of the foot, where it passes anteriorly to insert on the great toe (hallux).

Bunions are a deformity in the foot anatomy that causes the big toe to point toward the second one. This causes a bump on the edge of the foot at the joint of the big toe. Hammer toe is a deformity of the second, third or fourth toes that cause the toes to bend down like a claw.

Origin and insertion Flexor carpi ulnaris originates with two heads which are linked by a tendinous arch. The heads are named according to the bones they attach to; ... The more extensive ulnar head originates from the olecranon and proximal part of the posterior border of ulna.

Orbicularis Oris Origin & Insertion Specifically, this muscle originates from the mid-line of the mandible and maxilla. ... From the mandible and maxilla, the orbicularis oris muscle then travels forwards and inserts right into the tissues of the upper and lower lips.

In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the femoral triangle.

Origin of the Triceps Brachii The lateral head originates from the back surface of the humerus, just above the radial groove. The long head originates from the infraglenoid tubercle of the scapula. The glenoid cavity is a round, concave portion of the scapula where the head of the humerus meets with the scapula.

A: A corn forms as the skin responds to friction as it occurs from shoe pressure against bony prominences of the foot or toes. A bunion forms as the first metatarsal bone (the long bone behind the big toe) spreads outward from the foot causing a bump to appear. The big toe often then bends toward the lesser toes.

Babinski sign occurs when stimulation of the lateral plantar aspect of the foot leads to extension (dorsiflexion or upward movement) of the big toe (hallux). Also, there may be fanning of the other toes. This suggests that there is been spread of the sensory input beyond the S1 myotome to L4 and L5.

The toes are, from medial to lateral: the first toe, also known as the hallux ("big toe", "great toe", "thumb toe"), the innermost toe; the second toe, ("long toe", "pointer toe"), the third toe, ("middle toe", "long toe");

As the cartilage erodes, the bones in the joint rub together, causing pain and stiffness. In some cases, patients develop a bump at the base of the big toe called a bone spur (extra bone growth) than may resemble a bunion.

Insertion: Deltoid tuberosity of humerus. Function: Prime mover of arm abduction.

The Ankle Joint. The ankle joint (or talocrural joint) is a synovial joint located in the lower limb. It is formed by the bones of the leg (tibia and fibula) and the foot (talus). Functionally, it is a hinge type joint, permitting dorsiflexion and plantarflexion of the foot.

CRURAL MUSCLES FACTS From there, it diverges into four different directions, reaching out to attach to the bone structure of the toes II through V. The flexor digitorum longus thus affect numerous joints. These include flexing of the toes, helping the process of plantar flexing in a small manner, and foot inversion.

It originates at the inferior pubic ramus, the ischial ramus and the ischial tuberosity and inserts both at the linea aspera (“fleshy insertion”) and the medial epicondyle (“tendinous insertion”).

A bunion is a bony bump that forms on the joint at the base of your big toe. It occurs when some of the bones in the front part of your foot move out of place. This causes the tip of your big toe to get pulled toward the smaller toes and forces the joint at the base of your big toe to stick out.

Origin: (proximal attachments): Anterior and lateral surfaces of shaft of femur. Insertion: (distal attachments): Quadriceps tendon to base of patella and onto tibial tuberosity via the patellar ligament.

The brachialis muscle originates from the anterior surface of the distal half of the humerus, just distal to the insertion of the deltoid muscle. It is also attached to the intermuscular septa of the arm on either side, with a more extensive attachment to the medial intermuscular septum.
