What you will learn
- Distinguish the dorsal and plantar groups, then locate the three plantar groups.
- Describe the attachments, actions, and innervation of the dorsal and plantar foot muscles.
- Relate the plantar layers to toe movements and support of the plantar arch.
- Distinguish intrinsic foot muscles from extrinsic muscles that arise in the leg.
Course outline
Reading the foot by groups and layers
An orientation map distinguishes the dorsal muscles, the three plantar groups, and the extrinsic muscles extending from the leg.
8 min
The two short extensors on the dorsum
Extensor hallucis brevis and extensor digitorum brevis are described through their attachments, actions, and deep fibular innervation.
12 min
The medial and lateral plantar groups
The muscles along the two borders of the foot organize movements of the hallux and the fifth toe.
20 min
Superficial and middle plantar layers
Flexor digitorum brevis, quadratus plantae, and the lumbricals connect toe flexion, correction of tendon direction, and support of the plantar arch.
18 min
The deep layer: plantar and dorsal interossei
The two interosseous groups attach to metatarsals and proximal phalanges to act on flexion and on spreading or bringing the toes together.
16 min
Overall foot function and clinical landmarks
Intrinsic and extrinsic foot groups are placed within ankle and toe movements, posture, balance, and the analysis of motor deficits.
