The navicular bone has two functions: * To protect the joint and tendons from pressure and concussion (the navicular bone acts as a pulley on the deep digital flexor tendon, which takes some of the stress off the coffin bone). * To act as a valve for blood flow to the coffin bone and corium inside the hoof. reference: http://www.recoveryeq.com/navicular_horses.htm
A horse has 4 navicular bones and they are located in the hoof
Navicular bone is situated on the medial side of foot. The function of the navicular bone is to distribute the weight of the body evenly through the bones in the foot. Arteries running through the foot are also held together by these bones.

Like other tarsal bones, this bone plays a role in motion and support of the body. Additionally, the medial cuneiform touches four other bones: the intermediate cuneiform bone, the navicular, and two metatarsal bones.
There are seven tarsal bones: three cuneiform bones, the cuboid, navicular, talus, and calcaneus.
Tarsal bones. Individually they are the Talus, Calcaneus, Navicular, Cudboid and the Cuneforms 1-3.
The navicular bone is sometimes referred to scaphoid bone, which is one of the carpal bones in the wrist. It is also called the radiocarpal joint when it is associated with th radius and the lunate, another carpal bone. The three bones the form an ellipsoidal joint.
The 'tarsus' is a cluster of seven articulating bones in each foot. The bones that make up the tarsus, i.e. tarsal bones are: medial cuneiform, intermediate cuneiform, lateral cuneiform, navicular, cuboid, talus, and calcaneus.
The Tarsus consists of 7 bones in the foot: talus, calcaneus, navicular, cuboid, medial cuneiform, intermediate cuneiform, lateral cuneiform.
The tarsal bones are the bone of the ankle, heel and upper foot. Technically the ankle joint is the connection between the tibia and fibula (leg bones) and the talus, or ankle bone.
The small bones in the foot and ankle are called tarsal bones. There are seven tarsal bones: calcaneus, talus, cuboid, navicular, and the three cuneiform bones (medial, intermediate, and lateral).
