Anatomy 1.4
Topographical Anatomy
| Question | Answer |
|---|---|
| Topographical Anatomy/Surface Anatomy | The study of the structure of the body with emphasis on superficial landmarks, such as anatomical guides, linear guides, and anatomical limits. |
| Anatomical Guide | The method of locating one structure in relation to another adjacent & more prominent structure. |
| Anatomical Limit or Extent | The point of origin and termination of a structure in relation to adjacent structures. |
| Linear Guide | A line drawn or visualized on the surface of the skin, which represents the approximate location of some deeper lying structure. |
| Anterior Cervical Triangle | A topographical area on the anterior portion of the neck. |
| How many boundaries does the Anterior Cervical Triangle have? | Three: superior, lateral, medial |
| Superior Boundary or Base of the Anterior Cervical Triangle | This boundary is formed by the inferior border of the mandible. |
| Lateral Boundary of the Anterior Cervical Triangle | This boundary is formed by the SCM muscle. |
| Medial Boundary of the Anterior Cervical Triangle | This boundary is formed by the mid-line of the neck. |
| SCM muscles | Sternocleidomastoid muscle |
| What are the major contents of the Anterior Cervical Triangle? | The Common Carotid Artery, the Internal Jugular Vein, and the Vagus Nerve. |
| the Common Carotid Artery | Lies medial and deep to the Internal Jugular Vein, contained within the Anterior Cervical Triangle. |
| the Internal Jugular Vein | Lies lateral and superficial to the Common Carotid Artery, housed within the Anterior Cervical Triangle. |
| the Vagus Nerve | Lies posterior and in between the Common Carotid Artery and the Internal Jugular Vein. |
| the Carotid Sheath | This sheath bundles the common carotid artery, internal jugular vein, and the vagus nerve, and it arises from the deep cervical fascia. |
| the Mandible | The lower jaw. |
| Where is the superior part of the mandible? | This is the area of the lower jaw which holds the lower set of teeth. |
| Where is the inferior part of the mandible? | This area of the lower jaw is the jaw line, closest to the neck. |
| the Jugular Notch of the Sternum | The hollow depression in the center of clavicle. |
| What is the Sternum? | the Breastbone |
| Mastoid Process of the Temporal Bone. | The hard round bone located behind the ears. |
| Axilla (Axillary Space) | The small hollow space beneath the arm, where it joins to the the body by the shoulders. AKA, the armpit! |
| Axillary Artery | Lies lateral and deep to the Axillary Vein, housed within the Axilla. |
| Axillary Vein | Lies medial and superficial to the Axillary Artery. |
| Brachial Plexus | This is a network of fibers that originates from the ventral branches of the last four cervical (C5-C8) and first Thoracic (T1) spinal nerves. This network supplies the shoulders, arms and chest. |
| Femoral Triangle/Scarpa's Triangle | This area is located in the anterior superior portion of the upper 1/3 of the thigh. |
| Superior Boundary or Base of the Femoral Triangle | This border is formed by the inguinal ligament. |
| Lateral Boundary of the Femoral Triangle | This border is formed by the sartorius muscles |
| Medial Boundary of the Femoral Triangle | This border of the Femoral Triangle is formed by the adductor longus muscle. |
| Femoral Vein | This lies medial and deep to the femoral artery. |
| Femoral Artery | This lies lateral and superficial to the femoral vein. |
| Femoral Nerve | The nerve within the Femoral Triangle. |
| How many boundaries or borders does the Femoral Triangle have? | Thee: the Superior Boundary, the Lateral Boundary, and the Medial Boundary. |
| VAN | Vein, Artery, Nerve. (use as a tip for remembering the contents of the femoral triangle, going from medial to lateral) |
