02/12/23 Lower limb II: knee to foot: part 4 Learning objective: discuss the compartment of the leg and their associated movements and function. Learning objective: describe the attachments and function of the major muscles of the lower limb. Compartments of the leg: Anterior, posterior ( split into 2 layers ) and lateral. Ufg Lateral compartment: Pair of foot evertors: 1. Fibularis longus. 2. Fibularis brevis. Anterior compartment: Function: Dorsi exion and inversion of the ankle as well as extension of the toes. 1. Tibialis anterior. This is a primary Dorsi exion and invertor. 2. Fibularis tertius. big toe 3. Extensor hallucis longus ( extends big toe only ). 4. Extensor digitorum longus. Posterior compartment: super cial layer Function: plantar exion and exion of the knee. Triceps surae= 3 headed calf. 1. Gastrocnemius ( 2 heads ). 2. Soleus ( 1 head deep to the gastrocnemius). 3. Plantaris. Posterior compartment: deep Function: plantar exion and inversion. Flexion of the toes. 1. Tibialis posterior. 2. Flexor hallucis longus. 3. Flexor digitorum longus. 4. Popliteus.
