Osteo of Ankle and Foot

The video tutorial covers the anatomy of the lower leg and foot, focusing on the tibia, fibula, tarsals, metatarsals, and phalanges. It explains the landmarks and functions of these bones, their role in forming joints, and the importance of the interosseous membrane. The tutorial also discusses the structure and function of the foot's arches, highlighting the plantar fascia's role in maintaining stability and the windlass mechanism's significance during movement.

What is the primary function of the tibial tuberosity?

• Support for the ankle joint

• Protection of the common fibular nerve

• Articulation with the fibula

• Attachment point for the quadriceps femoris muscle group

What is the function of the interosseous membrane between the tibia and fibula?

• To anchor the tibia and fibula together

• To protect the ankle joint

• To support the knee joint

• To provide a surface for muscle attachment

Which tarsal bone bears the majority of the body's weight?

• Calcaneus

• Cuboid

• Talus

• Navicular

Which bone is located just in front of the talus?

• Medial cuneiform

• Calcaneus

• Navicular

• Cuboid

How many phalanges are present in the human foot?

• 16

• 10

• 12

• 14

What is the role of the plantar aponeurosis in the foot?

• It articulates with the talus

• It forms the heel bone

• It supports the longitudinal arches

• It connects the tibia and fibula

Which mechanism involves the extension of the great toe to increase the foot's arch?

• Windlass mechanism

• Mortise joint mechanism

• Interosseous mechanism

• Cuneiform mechanism
