2024年3月1日 · There are ten intrinsic muscles located in the plantar aspect (sole) of the foot. They act collectively to stabilise the arches of the foot and individually to control movement of the digits. They are innervated by the medial or lateral plantar nerves – which are branches of …

2023年10月12日 · The term "Plantar" specifically pertains to the underside of the foot. The plantar surface is what makes contact with the ground when a person is standing, walking, or running. On the other hand, "Dorsal" generally applies to the upper side or backside of an organism.

The plantar ligaments are stronger than those on the dorsal side (Figure 12 & 13). The Lisfranc ligament is a strong band of tissue that connects the medial cuneiform to the base of the second metatarsal.

The muscles along the dorsal side of the foot (a) generally extend the toes while the muscles of the plantar side of the foot (b, c, d) generally flex the toes. The plantar muscles exist in three layers, providing the foot the strength to counterbalance the weight of the body.

The foot can be divided into two main parts - the sole or plantar region, which is the part of the foot contacting the ground, and the dorsum of the foot or the dorsal region, which is the part directed superiorly.

2024年9月23日 · The first MTP joint, with its more extensive articular surface on the anterior (plantar) aspect of the metatarsal than on the posterior (dorsal), allows for a greater freedom of motion, and its anterior (plantar) surface forms two grooves for …

2024年3月4日 · The fourth layer comprises the plantar and dorsal interossei muscles, which abduct and adduct the toes, respectively. These also assist with maintaining balance and distributing weight across the foot.

2023年10月19日 · Plantar refers to the sole of the foot, while Dorsal refers to the back or upper surface of an organism. Plantar is a term primarily associated with the bottom or sole region of the foot. Dorsal, on the other hand, often denotes the back or upper surface of an organism, be it human or animal.

2021年2月26日 · The intrinsic foot muscles can be divided into two main groups, plantar and dorsal. The dorsal group consists of extensor digitorum brevis and extensor hallucis brevis which both act to extend the toes.

During plantar flexion, the sole of the foot angles downward toward the calf, decreasing the angle between those two surfaces, leaving the toes pointing farther away from the body. When you perform calf raises in the gym or walk on your tip toes, you plantar flex the foot.
