**.Thorax Abdomen** - **The ribs** - - **Orientation of the Tubercle** The tubercle of the rib is a key anatomical feature located on the posterior surface of each rib, specifically at the junction of the neck and body. ** Location**: - ** Articular Part:** - **Non-Articular Part** - **The subcostal muscles are located in the posterior thoracic wall and play a role in respiration** **Origin** ** Location** - **Insertion** - ** Function**: - **Innervation Nerve Supply:** - **Function** - **thymus gland (location,and how many thymus)** **Location** The location of your thymus gland is in your upper chest behind your breastbone (sternum). It sits between your lungs in a part of your chest called the mediastinum. - - **Layers of Your esophagus each layer what it contains where are the blood vessels** - - - - **Where in the heart your tricuspid valve located** - **right coronary artery does he provide anterior branches** - **Conus branch**: - **Anterior ventricular branches** - **Right marginal artery:** - **Sinoatrial nodal artery** - **Atrioventricular nodal artery** - **Rectus Abdominis Muscle ** - **Function** - **Muscles of iliacus muscle** - - **Body of the pancreas** The body of the pancreas is the middle section of the pancreas, located between the head and the neck. **The pancreas is a flat, pear-shaped gland that runs across the upper abdomen, behind the stomach,** **Head** - **Neck** - **Body** - **Tail** - **What is the lateral branch of aorta** The lateral branches of the aorta are primarily responsible for supplying blood to various organs and structures in the body. These branches can be categorized based on their location and function: **Lateral Branches of the Aorta** **1.Intercostal Arteries** Origin - ** Function**: **Supply blood to the intercostal muscles and skin of the thorax.** **2.Renal Arteries** Origin: Arise from the abdominal aorta at the level of L1-L2. ** Function**: **Supply blood to the kidneys.** **3.Gonadal Arteries (Testicular and Ovarian)** Origin: Arise **from the abdominal aorta, typically below the renal arteries**. **Function**: - **4.Lumbar Arteries Origin**: - **Function** - These lateral branches play crucial roles in delivering oxygenated blood to vital organs and tissues throughout the body. **Where is the descending colon** **Location** - **Length** - **Function** - **Kidney highlighting about anatomic description** - - ***Lymph nodes play a crucial role in the lymphatic system by filtering lymph fluid and facilitating immune responses.*** **Cervical Lymph Nodes:** - **Axillary Lymph Nodes:** - **Inguinal Lymph Nodes:** - ** Para-aortic (Lumbar) Nodes:** - These nodes filter harmful substances and help prevent infections by producing lymphocytes Paraaortic nodes, iliac nodes, preaortic nodes, and celiac nodes are **all part of the lymphatic system, which helps with immune response, trapping microorganisms,** **Paraaortic Nodes** - **Iliac Nodes:** - **Preaortic Nodes:** - **Celiac Nodes:** -
