# Blood Supply of Hind Limb ### Diagram: Blood supply of the hind limb This diagram depicts the blood circulation in the hind limb of a mammal. - **Arteries**: The diagram illustrates the course of various arteries, showing their branching and connections. - **Venous supply**: The diagram doesn't show the venous supply. - **Regions**: The diagram highlights key regions of the limb, including the pelvis, femur, knee, and lower leg. - **In Males**: The diagram shows the course of the *circumflex* and *femoral* arteries, showing their branches and how they connect to the *popliteal* and *tibial* arteries. - **In Females**: The diagram shows the blood supply in females, including the *middle uterine* artery, with its branches. ### Femoral Canal: **Muscles which make femoral canal** 1. **M. Sartorius**: Cranially 2. **M. Pectineus**: Caudally 3. **M. Iliopsoas and M. Vastus Medialis**: Laterally 4. **Femoral Fascia and M. Gracilis**: Medially **Femoral Canal Contains:** 1. **Femoral Artery** 2. **Femoral Vein** 3. **Saphenous Nerve** 4. **Deep Inguinal Lymph Node** **The most important branches of the femoral canal are:** 1. **Descending Genicular Artery** 2. **Caudal Femoral Artery** ### Arteries: - **Aorta Artery:** - To organ: **Visceral Branch** - To Muscle: **Parietal Branch** - **Renal Artery:** - Paired - To Kidney: **Visceral** - The *renal* artery branches into several smaller arteries that supply the kidney. - **Ovarian Artery**: - Paired - To Ovary: **Visceral** - The *ovarian* artery branches into several smaller arteries supplying the ovaries. - **Cranial Mesenteric Artery**: - Single - To Intestine: **Visceral** - The cranial mesenteric artery supplies the gut. ### Blood Supply of Lower Hind Limb **From Popliteal Artery:** 1. **Cranial Tibial Popliteal Artery** 2. **Dorsal Pedal Artery** **From Caudal Tibial Popliteal Artery:** 1. **Caudal Tibial Popliteal Artery** 2. **Medial Planter Artery** 3. **Lateral Planter Artery** 4. **Proximal Deep Planter Arch** 5. **Distal Deep Planter Arch** 6. **Superficial Planter Arch** 7. **Lateral Planter Proper** 8. **Medial & Lateral Planter with proper digits** ### Diagram: Blood supply of the lower hind limb - **Arteries**: The diagram illustrates the course of various arteries in the lower hind limb, showing their branching and connections. - **Regions**: The diagram highlights key regions of the lower hind limb, including the knee, tibia, fibula, and foot. - **Arches**: The diagram shows the formation of the *proximal deep planter* and *distal deep planter* arches, important for blood supply to the foot. - **Digits**: The diagram also shows how the arteries branch to supply the individual digits of the foot via the *medial planter proper*, *lateral planter proper* and branches. ### Aorta in body: - The *aorta* is the main artery in the body. - It originates from the heart and branches into various smaller arteries. - The diagram shows the *ascending*, *aortic arch*, and *descending aorta*. - **Descending aorta**: further branches into the *thoracic aorta* and *abdominal aorta*. - The *abdominal aorta* branches into the *external iliac artery* and the *internal iliac artery*, which supply the pelvic region. - The diagram also shows the *diaphragm muscle*.
