Question restatement: Which of the following is an intrinsic muscle of the foot?

Observation about provided data: The answer list contains only 'Flexor digitorum brevis m.' as the answer, but there are no answer options supplied to compare against. Because the actual distractors or alternatives are missing, we cannot methodically evaluate each option against the others. Nevertheless, we can still reason about the core concept.

Key concept: Intrinsic foot muscles are those that originate and insert within the foot itself, acting primarily on the foot and toes. They are contained entirely within the sole and include muscles such as the flexor digitorum brevis, abductor hallucis, abductor digiti minimi, lumbricals, and the plantar interossei and dorsal interossei. In contrast, extrinsic foot muscles originate in the leg (proximal to the ankle) and insert into the foot, such as the flexor digitorum longus, flexor hallucis longus, peroneus longus, tibialis posterior, and others.

Option analysis (based on the correct identification of intrinsic status, and general knowledge of intrinsic vs extrinsic):
- If the option presented is Flexor digitorum brevis m., this muscle is indeed intrinsic to the foot. It originates from the calcaneus and inserts into the digits, functioning to flex the lateral four toes at the proximal interphalangeal joints, primarily within the sole of the foot. This satisfies the definition of an intrinsic muscle.
- Since there are no other options shown, we cannot critique or distinguish alternative choices. Typically, an incorrect option would be a muscle that originates outside the foot (an extrinsic muscle) or a muscle that is not considered a primary intrinsic muscle (for example, some deep extrinsic muscles may also influence toe movement but originate in the leg).

Bottom line on the given statement: The statement that Flexor digitorum brevis is an intrinsic muscle of the foot aligns with anatomical definitions, because it originates and inserts within the foot itself and acts on the toes from within the sole.

Note: If you obtain the complete list of options, you can compare each option against the intrinsic/extrinsic criteria and confirm which choices are intrinsic versus extrinsic, reinforcing why Flexor digitorum brevis m. belongs in the intrinsic category.
