What are the Lumbrical muscles of the foot? Lumbricals are the four small muscles located in the sole. Following the arrangement of plantar foot muscles into four layers (superficial to deep), the lumbricals and quadratus plantae include the second layer. The lumbrical muscles extend at the interphalangeal joints and flex and adduct the lateral four…
What is the Quadratus Plantae muscle? The Quadratus Plantae muscle is a deep muscle located in the foot. It is situated in the sole of the foot and lies deep to the muscles of the first layer (intrinsic muscles) of the foot. The Quadratus Plantae muscle is named based on its square or quadrilateral shape….
What is the Abductor digiti minimi muscle of the foot? Abductor digiti minimi is a unipennate muscle found in the lateral aspect of the sole. As there are horizontal and vertical sets of foot muscles into four layers and three groups respectively, the complete address of this muscle is that it belongs to them; The…
Introduction The Multifidus muscle is a group of short, triangular muscles that along with the semispinalis and rotatores include the transversospinal group of deep back muscles. They are the thickest muscles in the transversospinal group and are shorter than semispinalis, but lengthier than rotatores. The Multifidus muscles are located on either side of the vertebral…
What is the Flexor digitorum brevis muscle? Flexor digitorum brevis (FDB) is a broad muscle located deep in the sole. Because the plantar foot muscles can be broken down into groups (medial to lateral) or layers (superficial to deep), there are two ways to specify the exact location of the flexor digitorum brevis: Along with…
What are the Dorsal interossei muscles of the foot? The four feather-like muscles in the center of the sole are called dorsal interossei. Dorsal interossei can be grouped because the plantar foot muscles can be isolated into layers (superficial to deep) or groups (medial to lateral). The central plantar muscles, alongside the flexor digitorum brevis,…
What is Abductor hallucis muscle? Abductor hallucis is a fusiform muscle found superficially and medially in the foot. Abductor hallucis, along with flexor digitorum brevis and abductor digiti minimi, make up the first (most superficial) layer of plantar foot muscles, observing the variety of superficial to deep muscles. On the further hand, if the foot…
What is the Extensor digitorum brevis muscle? The extensor digitorum brevis muscle is a muscle located on the top of the foot. It is situated between the tendons of the extensor hallucis longus and the extensor digitorum longus muscles. Functionally, the extensor digitorum brevis muscle helps with the extension of the toes, specifically the second,…
What is Extensor Hallucis Brevis Muscle? The extensor hallucis brevis muscle is one of the muscles located in the human foot. It is part of the extensor muscle group and is responsible for extending and dorsiflexing the big toe. Originating from the calcaneus (heel bone), the extensor hallucis brevis muscle runs along the top of…
What is Fibularis (Peroneus) longus muscle? Fibularis (Peroneus) longus muscle is a long muscle found superficially in the lateral part of the leg, together with the fibularis brevis muscle. The Fibularis longus extends from the proximal part of the fibula to the medial cuneiform and the first metatarsal bones. This muscle is innervated by the…
