Flexor Hallucis Brevis Muscle Anatomy: Origin, Insertion, Action and Innervation
Origin: Lateral head: medial part of the plantar surface of the cuboid, posterior to the groove for the peroneus longus tendon, and from the adjacent part of the lateral cuneiform.
Medial Head: a deep attachment that is continuous with the lateral division of the tendon of tibialis posterior, and a more superficial attachment to the middle band of the medial intermuscular septum of the foot.
Insertion: The belly divides into medial and lateral tendons. These tendons are attached to the sides of the base of the proximal phalanx of the great toe, with a sesamoid bone usually occurring in each tendon near its point of attachment. At the points of attachment to the proximal phalanx, the medial tendon blends with abductor hallucis, and the lateral tendon with adductor hallucis.
Action: Flexion of the great toe at the metatarsophalangeal joint, supports the medial longitudinal arch of the foot.
Innervation: Medial plantar nerve (S1, 2)
Blood Supply: Branches from the posterior tibial artery
Synergist: Adductor hallucis
Primary Actions of the Flexor Hallucis Brevis:
1. Flexion of the great toe at the metatarsophalangeal jont
- Agonists: Flexor Hallucis Longus
- Antagonists: Extensor Hallucis Longus, Extensor Hallucis Brevis
Secondary Actions of the Flexor Hallucis Brevis:
2. Supports the medial longitudinal arch of the foot
The Anatomy Coloring Book is one of the best study and reference books for beginning anatomy students. The diagrams are clearly labeled and allow you to see the relationship and placement of the various structures of the body. You will also be surprised how the act of coloring will help with recall. But this is not just a beginners book, it is also great for practitioners and therapists to have on hand to use with clients and patients to use as a visual reference.
Anatomy Books Specializing in the Feet
McMinn’s Color Atlas of Foot and Ankle Anatomy is a very good foot anatomy for students who need more than the very basics. The book filled with images including x-rays, images of the anatomy with cadavers, and live human models. I recommend this book not only to students but to medical professionals for the clear anatomical photos that are useful with patients. I also highly recommend this book for to massage therapists, personal and athletic trainers as it helps you develop the mind’s eye view of the soft tissues and bones that you will be treating. Also available in a Kindle Edition.
