What effect does the long digital extensor have on the tarsal & interphalangeal joints?
tarsal - flex
interphalangeal - extend
What are the attachments for fibularis longus?
extends from the lateral condyle of the tibia & proximal fibula TO the 4th tarsal bone, proximoplantar aspect of metatarsals
What action does fibularis longus have on the tarsal joints?
flex
What are the attachments of the gastrocnemius?
extends between the distocaudal femur TO the tuber calcanei
What action does the gastrocnemius have on the tarsal joints?
extend
What are the muscle attachments for superficial digital flexor?
extends between the distocaudolateral femur TO the tuber calcanei & the plantar surface of middle phalanges of digits 2-5
What action does the superficial digital have on the tarsal & proximal interphalangeal joints?
tarsal - extend
interphalangeal - flex
What are the attachments for deep digital flexor?
lateral head: attaches proximally to the proximocaudal tibia & fibula
medial head: attaches proximally to the proximocaudal tibia
BOTH attach distally to the plantar surface of the distal phalanges of digits 2-5 via a common tendon
What action does the deep digital flexor have on tarsal & interphalangeal joints?
tarsal-extend
interphalangeal-flex
What are the attachments for popliteus?
extends between the lateral epicondyle of the femur to the proximocaudal tibia
