DEFINITIONS II

Question 1

• articulation of a rounded metatarsal head with the respective concave base of a proximal phalanx, ex. The 2nd metatarsal head articulates with the 2nd
  proximal phalangeal base, etc.
• the sesamoids are included for the 1st metatarsophalangeal joint

Answer 1

Metatarsophalangeal Joints (MTPJs)

Question 2

• attaches near the articular margins (encloses most of the metatarsal head)
• lined with synovium
• supported by ligaments

Answer 2

Capsule

Question 3

• proximal and distal interphalangeal joints are identical

- capsules attach at the articular margins, are lined with synovium, and supported by ligaments

Answer 3

Interphalangeal Joints (IPJs)

Question 4

• articulation of the bicondylar convex head of a proximal phalanx with the respective bicondylar concave base of a middle phalanx, ex. the 3rd proximal phalangeal head articulates with the middle phalangeal base of toe 3, etc.

Answer 4

Proximal Interphalangeal Joints (PIPJs)

Question 5

• articulation of the bicondylar convex head of a middle phalanx with the bicondylar concave base of a distal phalanx, ex. the middle phalangeal head of the 5th toe articulates with the base of the distal phalanx of the 5th toe, etc.

Answer 5

Distal Interphalangeal Joints (DIPJs)

Question 6

• articulation of the bicondylar convex head of the hallucal proximal phalanx with the bicondylar concave base of the 1st distal phalanx

Answer 6

Interphalangeal Joint of the Hallux
