i. Fibula
j. Tibia
k. Tarsal bone
Work Step by Step
The coxal bones are the hip bones. each one is made up of three fused bones--the ilium, the ischium and the pubic bone. The pubic bones -- left and right superior rami- meet anteriorly/ventrally ( just distal to the urinary bladder in males) to form the pubic symphysis joint. A pad of fibrocartilage connects the pubic bones.
The patella or kneecap is a flattish, trianguloid sesamoid bone that lies in front of and protects the anterior articular surfaces of the knee joint; it is located within the tendons of the quadriceps femoris muscles, and it articulates with the femur.
Metarsal bones. The metarsal bones are located between the phalanges of the toes and the bones of the mid and hind foot; they do not have specific names, but are numbered from big toe (hallux ) side --I ,II, III, IV and V ( first, second, third, fourth and fifth) metatarsal.
Phalanges. These are the bones of the toes; there are 14 phalanges ( sing. phalanx) in each foot.
Humerus . This is the arm bone proper. It is the largest bone of the forelimb and extends from shoulder joint to elbow joint.
Ulna. This is the larger of the two bones of the fore arm. It extends from the elbow joint to the wrist joint.
Radius: This is the smaller of the bones of the forearm. It also extends from elbow to wrist . There is a fibrous connection, the interosseous membrane, that runs between the inner longitudinal aspects of ulna and radius.
Femur. This is the thigh bone . It is the longest and strongest bone in the body . The head of the femur fits into the acetabulum and the bone lies between the hip joint and the knee joint.
Fibula. The fibula is the smaller of the two leg bones. It is situated on the lateral (calf) side of the larger tibia.
Tibia. This is the shin bone. It is located on the medial side of the leg; it is considered the second largest bone in the body and is
connected to the fibula by an interosseous membrane.
Tarsal bone. The tarsal bones are located between the metatarsals and the distal ends of the tibia and fibula The tarsus is composed of seven bones: the bones of the midfoot-- the three cuneiforms, the cuboid and the navicular; the bones of the hindfoot--the talus and the calcaneus. The talus supports the tibia and fibula and the calcaneus ( the largest tarsal bone) together with the distal ends of the tibia and fibula form the ankle.
