Multiple Choice
The insertion of the fibularis longus is the __________.
A
tibial tuberosity
B
medial cuneiform and base of the first metatarsal
C
lateral malleolus
D
calcaneal tuberosity
Verified step by step guidance
1
Understand the anatomy of the fibularis longus muscle: It is a muscle located in the lateral compartment of the leg and plays a role in plantarflexion and eversion of the foot.
Review the concept of muscle insertion: The insertion is the point where the muscle attaches to the bone that moves during contraction. For the fibularis longus, this is important for its function in stabilizing the foot.
Identify the correct anatomical landmarks: The medial cuneiform and the base of the first metatarsal are located in the foot and are key structures involved in the fibularis longus insertion.
Eliminate incorrect options: The tibial tuberosity, lateral malleolus, and calcaneal tuberosity are not associated with the fibularis longus insertion. These structures are related to other muscles or functions.
Conclude that the insertion of the fibularis longus is the medial cuneiform and the base of the first metatarsal, as these are the correct anatomical points for this muscle.
