NEET PG DENTAL EXAM

Detailed explanation-1: -The five metatarsal bones are numbered from one through five, medially to laterally, starting at the hallux (great toe). Each of the metatarsal bones articulates proximally with a tarsal bone and distally to one of the five phalanges of the foot, making the metatarsophalangeal (TMP) joint.

Detailed explanation-2: -The five metatarsals are dorsal convex long bones consisting of a shaft or body, a base (proximally), and a head (distally).

Detailed explanation-3: -The metatarsal bones are convex on their dorsal surfaces but concave on their plantar surfaces. The proximal base articulates with one or more of the distal tarsal bones; namely the cuboid and the cuneiform bones.

Detailed explanation-4: -Its proximal portion is divided into three parts: the tuberosity, metaphysis, and proximal diaphysis (figure 2). The base, or proximal portion, of the fifth metatarsal articulates medially with the fourth metatarsal, while the tuberosity articulates proximally with the cuboid.
