Name the muscle and its origin, insertion, innervation, and action

Extensor hallucis brevis muscle
Origin: Dorsal portion of calcaneus
Insertion: Dorsal surface of the base of the proximal phalanx of hallux
Innervation: Deep peroneal nerve
Action: Extends hallux
Name the muscle and its origin, insertion, innervation, and action

Extensor digitorum brevis muscle
Origin: Dorsal and lateral surface of the calcaneus

Name the muscle and its origin, insertion, innervation, and action

Dorsal interossei muscles of the foot
Origin: Adjacent sides of the two metatarsal bones between which it is located
Insertion: Bases of the proximal phalanges of the second, third, and fourth toes and into the aponeurosis of the tendons of the extensor digitorum longus
Innervation: Lateral plantar nerve
Action: Flexes the MTP joints. Extends the PIP joints and the DIP joints. Abduct at the MTP joints of the third and fourth toes. Because there is a pair of dorsal interossei muscles attached on both sides of the second toe, simultaneous contraction of these muscles results in no movement

Origin (oblique head): Bases of metatarsals 2-4, sheath of tendon of peroneus longus
Origin (transverse head): Plantar MTP ligaments of toes 3-5
Insertion: Lateral side of hallux
Innervation: Lateral plantar nerve
Action: Adducts hallux
Name the muscle and its origin, insertion, innervation, and action
