Demonstration of Lower Limb Soft Tissues - Part 3

This detailed demonstration by Dr. Amber Rana from King George's Medical University focuses on identifying and describing the structures of the lateral compartment of the leg, posterior compartment of the leg, and dorsum of the foot. It covers boundaries, muscles, nerves, and vessels present in each region, such as the peroneus longus and brevis muscles in the lateral compartment and the gastrocnemius, soleus, and tibialis posterior muscles in the posterior compartment.

1. DEMONSTRATION OF SOFT PARTS OF LOWER LIMB PART 3 BY- Dr. Amber Rana JR3 Department of Anatomy King George s Medical University

2. Objective : To identify and describe the various structures of the following region:- Lateral compartment of leg Posterior compartment of leg Dorsum of foot

3. Lateral Compartment of Leg: Boundaries: - anteriorly: Anterior intermuscular septum Posteriorly: Posterior intermuscular septum Medial: Lateral surface of fibula Lateral: Deep fascia Structures present are:- Muscles: Peroneus longus and Peroneus brevis Nerves: Superficial peroneal nerve Vessels: Peroneal artery

4. Peroneus brevis Lateral malleolus Peroneus longus

5. Peroneus Longus Origin: Head of fibula upper and middle 1/3rd of the lateral surface of shaft of fibula Insertion : base of first metatarsal, medial cuneiform. Nerve: superficial peroneal nerve Action: Planterflexion, eversion of foot

6. Peroneus brevis Origin: Anterior half of middle 1/3rd and whole lower 1/3rd of lateral surface of shaft of fibula, Anterior and posterior intermuscular septum Insertion : lateral side of the base pf the 5th metatarsal bone vessel :peroneal artery Nerves: superficial peroneal (fibular)nerve Action: Planterflexion, eversion of foot

7. Posterior Compartment of leg Aka posterior compartment of leg Subdivided into 3 compartment : superficial, middle, and deep by 2 strong fascial septa Muscles of superficial compartment : Gastrocnemius, Soleus and Plantaris Nerve supply: posterior tibial nerve Action: planter flexion of foot (Both gastrocnemius and soleus) flexion at knee joint (gastrocnemius) Muscles of deep compartment: popliteus, FDL, FHL, Tibialis posterior

8. Lateral head Of gastrocnemius Medial head of gastrocnemius

9. soleus Proximal Lateral Medial Tendo achellis Distal

11. Dorsum of Foot Small muscle of foot is extensor digitorum brevis present on the dorsal side of foot .Its tendon are deep to the tendons of extensor digitorum longus. Its medial tendon is called extensor hallucis brevis.

12. Extensor digitorum longus Inferior Extensor retinaculum Extensor Hallucis Longus Tibialis Anterior Superior Extensor Retinaculum

15. Thankyou
