Question 13

Question 14

Phalanges of foot

Answer 14

The great toe (also called hallux) is digit number one, just as the thumb (pollex) is number one on the hand. It has only a distal and proximal phalanx.
The long toe is digit number two.
The middle toe is digit number three.
The ring toe is digit number four.
The pinky toe is digit number five.

Question 15

Talus

Answer 15

The talus is the ankle bone at the superior portion of the posterior tarsus, and it gets its name from a Latin word that means ankle. It articulates (forms a joint) with the tibia and fibula bones of the lower leg, as well as other tarsal bones. The tibia and fibula bones form that bony part on each side of your ankle, called the medial and lateral malleolus.

Question 16

Calcaneus

Answer 16

Inferior to the talus bone is the calcaneus bone, which forms the heel of the foot and is larger than any other tarsal bone.

Question 17

Navicular

Answer 17

The navicular bone gets its name from a Latin word that means “little ship.” This bone is always located on the same side as the big toe (medial side).

Question 18

Cuneiforms

Answer 18

(lateral, intermediate, and medial) – There are three cuneiform bones of the tarsus that begin at the medial (big toe) side of the foot. They get their name from a Latin word that means “wedge-shaped.” Medial means toward the midline or middle of the body, and this bone is going to be on the same side of the foot as the big toe. Intermediate means middle, and that’s where this cuneiform bone is located. And lateral means at or toward the side of the body or away from that midline, which is where this cuneiform bone is located.

Question 19

Cuboid

Answer 19

On the lateral side of the foot we have the cuboid bone. As the name suggests, it has a cube shape to it.
