Anatomy 1.4

Topographical Anatomy

QuestionAnswer
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)
