| Where is the spring ligament found? | Tuberosity of navicular and sustentacular tali |
| Where is the short plantar ligament found? | calcaneum to cuboid |
| Where is the long plantar ligament found? | calcaneal tubercles to beyond peroneal groove and has branches which connect to the 2nd, 3rd and 4th mets. |
| Which ligaments make up the deltoid ligament? (4) | anterior tibiotalar ligament, tibiocalcaneal ligament, posterior tibiotalar ligament and the tibionavicular ligament. |
| Which ligaments make up the lateral side of the ankle? | Anterior talofibular. Posterior talofibular. Calcaneofibular |

| Which bones make up the ankle joint? | tibia and talus |
| Which bones make up the sub-talar joint? | Talus and calcaneum. |
| Bifurcate ligament? | Y shaped, splits into two. Holds the calcaneum with the navicular and cuboid. |
| At which joints in the foot is it possible to demonstrate inversion? | sub-talar and mid-tarsal |
| Movement in knee? | Extension and Flexion |
| Movement in ankle? | Extension and flexsion |

| Distal IP joint | Dorsiflexion and Plantarflexion |
| What muscles make up the first layer of muscle? | Flexor digitorum Brevis Abductor Hallucis Abductor digit minimi |
| Origins of the muscles in the first layer? | Flexor D Brevis - Calcaneum tuberosities Abductor hallucis calcaneum too Abductor digiti minimi - calcaneum |
| Insertions of the first layer of muscle? | FDB - Middle phalanx of 234 and5 AH - Medial side of base of proximal phalanx of hallux ADM - Lateral side of base of proximal phalanx of little toe. |
| Movements of muscles in the first layer. | FDB - flexsion of four toes AH - Abduct and flex big toe ADM - Abduct and flex little toe |
| 2nd layer of muscles (and tendons) | Quadratis plantae (Flexor accessories) Lumbricals Flexor digitorium longus Flexor hallucis longus |
| Origins of muscles from the 2nd layer | QP - calcaneum Lum- FDL tendon |
| Insertions of muscles in the 2nd layer | QP - FDL Lumbricals - SPLITS INTO 2 - dorsal expansion medial side and base of proximal phalanx. |
| Movement of 2nd layer of muscle | QP - assist the FDL in flexion Lumbricals - flexion of MPJ and extension of IPJ. |
| 3rd layer of muscle | Flexor hallucis brevis Flexor digiti minimi brevis Adductor Hallucis (Transverse and Oblique heads) |
| Origins of 3rd layer of muscle | FHB - Cuboid FDMB - base of 5th met head AH (transverse) - ,3,4 and 5 mpj joint capsules AH - (oblique) - 2,3,4 base of mets |
| Insertions of the 3rd group of muscles | FHB - base of proximal phalanx - splits in two FDMB - lateral base of 5th toe Adductor Hallucis (transverse head) - 3,4,5 of MPJ JOINT CAPSULE. OBLIQUE HEAD - base of 2,3,4 mets |
| Movements of muscles in the 3rd layer | FHB - flexion of 1st MPJ FDMB - flexion of 5th MPJ AH - adducts 1 MPJ |
| 4th layer of muscles | Plantar interossei - 3 muscles Dorsal interossei - 4 muscles |
| Origin of 4th layer | Plantar interossei - Bases and medial sides of mets 3-5. Dorsal interossei - Adjacent sides of mets 1 - 5. |
| Insertions of 4th layer | Planter I - medial sides of bases of proximal phalanges of toes 3 - 5. Dorsal I - medial side of proximal phalanx of second toe. Second to fourth toes - lateral sides of toes 2 to 4. |
| Movements of the 4th layer | Plantar - adducts toes 2-4 and flexes MPJ. Dorsal - abducts toes 2-4 and flexes MPJ |
| Muscles on the dorsum | Extensor hallucis brevis Extensor digitorum brevis |
| Origins of Dorsal side muscles | EDB AND EHB- Upper lateral side of calcaneum |
| iNSERTION OF DORSAL MUSCLES | EDB - 2,3,4 proximal phalanx EHB - Hallux (proximal) |
| Action of muscles dorsal side | Extension of MPJ |
