How are bones of the foot similar to bones of the hand?

There are 26 bones in the foot (compared to 27 in the hand) divided into three groups:
14 Phalanges
5 Metatarsals
7 Tarsals (compared to 8 carpals in the hand)

6

The dorsum or dorsal surface of the foot is:

The superior surface of the foot.

7

The plantar surface of the foot is:

Inferior or posterior aspect of the foot.

8

Phalanges of the foot (or digits) are also called

toes

9

The phalanges (toes) are numbered:

1-5

10

The first digit of the foot has ____ phalanges and are called_____ & ______.

2/proximal and distal

11

Second through fifth digit of the foot have ___ phalanges and they are called ____, _____, and ______.

3/proximal, middle and distal.

12

The head of the phalanx is:

the rounded distal portion.

13

The body (shaft) of the phalanx is:

Central portion.

14

The base of the phalanx is:

Expanded proximal portion.

15

Metatarsals are:

the bones of the instep, numbered 1-5, and consist of a head, body and base.

16

The 5 metatarsal heads form:

the "ball" of the foot.

17

Which metatarsal is the shortest and thickest?

the first

18

The base of the 5th metatarsal contains:

a prominent tuberosity.

19

The tuberosity on the base of the 5th metatarsal provides for:

attachment of a tendon.

20

The tuberosity on the base of the 5th metatarsal is a common site for:

fractures

21

The tuberosity on the base of the 5th metatarsal must be:

well visualized on the radiograph.

22

Interphalangeal joint (IP) is:

Between proximal and distal phalanges of the 1st digit.

23

Proximal interphalangeal joints (PIP) are:

Between proximal and middle phalanges 2-5.

24

Distal interphalangeal joints (DIP) are:

Between middle and distal phalanxes 2-5.

25

Metatarsophalangeal Joint (MTP joint) is:

Between heads of metatarsals and bases of phalanges.

26

Tarsometatarsal Joint (TMT joint) is:

Between tarsals and bases of metatarsals.

27

Sesamoid bones

Small, detached bones embedded in certain tendons.

28

Sesamoid bones of the lower limb:

Largest is patella, Two on plantar surface at head of 1st metatarsal. Medial side is tibial sesamoid, lateral side is fibular sesamoid.

29

Sesamoid bones of the upper limb:

Most often found on palmar surface near MCP joint.

30

Fractures of sesamoid bones in foot:

cause pain when bearing weight.
