The tibia supports the weight of the body and is the bone that articulates with the femur. The fibula is more slender and is a bone to which muscles attach. The top of the tibia is expanded into a triangular shape with the medial tibial condyle and lateral tibial condyle articulating with the condyles of the femur. The quadriceps femoris muscles attach to the tibial tuberosity on the anterior surface of the tibia just below the condyles. The anterior tibial crest is a large ridge that runs the length of the bone. At the terminal portion of the tibia is the medial malleolus. This process, along with the lateral malleolus of the fibula, join with the talus of the foot. The head of the fibula is proximal. It is a triangular region with a pointed apex. Label the tibia and fibula illustrations and color in the various regions of the bones.

Answer Key: a. Lateral tibial condyle, b. Medial tibial condyle, c. Tibial tuberosity, d. Apex, e. Head of fibula, f. Anterior tibial crest, g. Shaft of tibia, h. Shaft of fibula, i. Medial malleolus, j. Lateral malleolus

Tibial Crest



Color in the seven tarsal bones using different colors for each bone. The calcaneus is the heel bone and takes the major weight of the body during walking. The talus connects the foot to the tibia and fibula forming the ankle joint. The cuneiforms are so called because they are wedge-shaped bones and they form a natural arch of bone in the foot.

Note that each of the metatarsals and each of the phalanges has a distal head, a shaft, and a proximal base. Color all of the five metatarsals the same color. The first metatarsal is under the big toe and the fifth is under the smallest toe. Color all of the fourteen phalanges another color. All of the proximal phalanges are given the same letter in the illustration as are the middle and distal phalanges. Write proximal, middle, or distal in the appropriate space next to the toes. The big toe (hallux) has two phalanges while the other toes have three.

Answer Key:

1. Phalanges

2. Metatarsals

3. Tarsals a. Distal phalanges, b. Middle phalanges, c. Proximal phalanges, d. Head, e. Shaft, f. Base, g. First (medial) cuneiform, h. Second (intermediate) cuneiform, i. Third (lateral) cuneiform, j. Cuboid, k. Navicular, I. Talus, m. Calcaneus

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
