Anatomy of Lower Limb Bones Quiz

Carpal Bones

• The four bones in the proximal row of the carpal bones are not specified.
• The scaphoid bone is the largest and fuses with the lunate at its head portion.

Carpal Tunnel

• The tendons of forearm muscles are closely associated with the carpal bones due to the retinaculum.
• Carpal tunnel syndrome arises due to the narrowing of the carpal tunnel.

Pelvis

• The sacral promontory is the spine located above the tuberosity that constricts the pelvic outlet in women during parturition.
• The obturator foramen is the largest foramen in the entire skeleton that provides access for blood vessels and nerves to the ischium.
• The pubic symphysis is the joint that connects the two pubis of the hip bones.
• The pelvic brim is the boundary line that separates the pelvis into superior and inferior portions.

Femur

• The femur is regarded as the heaviest and strongest bone in the body.
• The region of the femur that immediately follows the neck is called the shaft or body.
• The condyles at the distal end of the femur tend to fuse with the condyles of the tibia.

Lower Limb

• There are 7 bones located in the ankle region of each lower limb.
• The fibula is regarded as the most slender bone of the body.

Ankle

• The malleolar fossa is the projection where fusion occurs between the talus of the ankle and the distal end of the fibula.
• There are 3 ankle bones (tarsal bones) that make up the proximal part of the foot.
• The calcaneus is the thick and largest bone of the ankle.
