What are the joints of the metatarsals?
They have three or four articulations: Proximally – tarsometatarsal joints – between the metatarsal bases and the tarsal bones. Laterally – intermetatarsal joint(s) – between the metatarsal and the adjacent metatarsals. Distally – metatarsophalangeal joint – between the metatarsal head and the proximal phalanx.
What type of joint is the foot joint?
The ankle joint (or talocrural joint) is a synovial joint located in the lower limb. It is formed by the bones of the leg (tibia and fibula) and the foot (talus). Functionally, it is a hinge type joint, permitting dorsiflexion and plantarflexion of the foot.
What are the 5 joints found in the foot?

- 1.2 Talocrural (TC) Joint.
- 1.3 Subtalar (ST) Joint Subtalar Joint.
- 1.4 Midtarsal (MT) Joint.
- 1.5 Tarsometatarsal (TMT) Joint Complex.
- 1.6 Metatarsophalangeal (MTP) Joints and Interphalangeal (IP) Joints.
What are the joints that are formed by the bones involved in the ankle foot and toes?
The foot and toe joints
- Talocalcaneonavicular joint: This synovial joint is formed between the talus and the calcaneus and the navicular bones.
- Calcaneocuboid joint: Another synovial joint, this one is formed between the front of the calcaneus and the posterior surface of the cuboid bone.
What’s the bone called on the side of your foot?
Cuboid. The cuboid bone is a square-shaped bone on the lateral aspect of the foot.
Why is my 2nd toe curling under?
In most circumstances, your second toe is curling because it is trying to stabilize your forefoot in gait. A bunion deformity (a.k.a. Hallux valgus) causes the weight to shift to the second MPJ (or knuckle). Over time, the flexor tendon causes the toe to curl and eventually a hammertoe can occur.
What are the articulations of the metatarsals in the foot?
They have three or four articulations: 1 Proximally – tarsometatarsal joints – between the metatarsal bases and the tarsal bones. 2 Laterally – intermetatarsal joint (s) – between the metatarsal and the adjacent metatarsals. 3 Distally – metatarsophalangeal joint – between the metatarsal head and the proximal phalanx.
How are the metacarpal bones and phalanges strengthened?
The joint is formed between the heads of the metacarpal bones and proximal phalanges. All of the five metacarpophalangeal joints are strengthened by a fibrous capsule. There are two collateral and one palmar ligament associated with each metacarpophalangeal joint.
How many metacarpophalangeal joints are there in the hand?
There are five metacarpophalangeal joints in each hand, each of which is a multiaxial diarthrodial- condyloid joint. The joint is formed between the heads of the metacarpal bones and proximal phalanges.
Where are the joints of the carpal bones located?
1 Articular surfaces. The CMC joints are connections between the distal surfaces of the four distal carpal bones and the surfaces of the metacarpal bases of the medial four metacarpal bones. 2 Joint capsule. 3 Ligaments. 4 Innervation 5 Blood supply. 6 Movements. 7 Muscles acting on the carpometacarpal joints.
