      The tendons split to give 2 insertions to either side of the base of the proximal phalanx

    Correct Answer
    D. The tendons split to give 2 insertions to either side of the base of the proximal phalanx
    Explanation
    The tendons of the flexor hallucis brevis split into two insertions, one on either side of the base of the proximal phalanx. This means that the tendon divides into two branches, each of which attaches to a different side of the bone. This allows for better control and coordination of movement in the hallux (big toe), as the tendons can exert force on both sides of the bone.

    • D.

      Transverse head : joint capsul & intermetatarsal ligaments of 2,3,4,5 oblique head: base of 2,3,4, 5 metatarsals

    Correct Answer
    A. Transverse head : joint capsul & intermetatarsal ligaments of 3,4,5 oblique head: base of 2,3,4 metatarsals
    Explanation
    The correct answer states that the origins of the adductor hallucis are the joint capsule and intermetatarsal ligaments of the 3rd, 4th, and 5th metatarsals for the transverse head, and the base of the 2nd, 3rd, and 4th metatarsals for the oblique head. This means that the transverse head of the adductor hallucis muscle originates from the joint capsule and ligaments between the 3rd, 4th, and 5th metatarsals, while the oblique head originates from the base of the 2nd, 3rd, and 4th metatarsals.

    Action of adductor hallucis

    • A.

      Abduction of 1st metatarsal phalangeal joint

    • B.

      Abduction of 5th metatarsal phalangeal joint

    • C.

      Adduction of 1st metatarsal phalangeal joint

    • D.

      Adduction of 5th metatarsal phalangeal joint

    Correct Answer
    C. Adduction of 1st metatarsal phalangeal joint
    Explanation
    The correct answer is adduction of 1st metatarsal phalangeal joint. The adductor hallucis is a muscle that is responsible for adducting the big toe towards the midline of the foot. This action occurs at the 1st metatarsal phalangeal joint, which is the joint between the base of the big toe and the first metatarsal bone. Therefore, the action of the adductor hallucis is adduction of the 1st metatarsal phalangeal joint.

    Which muscle insert into lateral side of the base of the proximal phalanx of the hallux

    • A.

      Adductor hallucis

    • B.

      Abductor hallucis

    • C.

      Flexor hallucis brevis

    • D.

      Both a and c

    • E.

      Both b and c

    Correct Answer
    D. Both a and c
    Explanation
    Both the adductor hallucis and the flexor hallucis brevis muscles insert into the lateral side of the base of the proximal phalanx of the hallux. The adductor hallucis muscle helps to adduct or bring the hallux towards the midline of the foot, while the flexor hallucis brevis muscle flexes the hallux or bends it downwards. Therefore, both of these muscles contribute to the movement and stability of the hallux. The abductor hallucis muscle, on the other hand, inserts into the medial side of the base of the proximal phalanx of the hallux, so it is not involved in this specific insertion site.
