Blood Vessels and Nerves
What is the Vertebrae Prominens?
The Spinous Process of C7
What is the special feature of the Spines of Cervical Vertebrae?
The are Bifid - They contain 2 different Spinous Processes
What curvature exists in the Cervical portion of the Vertebral Column?
Lordotic Curve (Inward Curve)
What 2 triangles can the neck be divided into? And what are they?
The Anterior Triangle
The Posterior Triangle
They are descriptive areas to help describe the position of various structures.
What forms the boundaries of the Anterior Triangle?
Anteriorly - The Midline
Superiorly - The Mandible Bone
Posteriorly - The Anterior Border of the Sternocleidomastoid Muscle
What forms the boundaries of the Posterior Triangle?
Posteriorly - The Trapezius Muscle
Inferiorly - The Clavicle
Anteriorly - The Posterior Border of the Sternocleidomastoid Muscle
What is contained within the Anterior Triangle?
a) The Common Carotid Artery
b) The External Carotid Artery
c) The Internal Carotid Artery
d) The Facial Artery
2. Veins :
a) The Internal Jugular Vein
b) The Facial Vein
a) Cranial Nerves 4, 5, 6, and 7
b) The Laryngeal Nerve
4. Lymph Nodes:
a) The Submandibular Lymph Nodes
b) The Submental Lymph Nodes
What is contained within the Posterior Triangle?
1. Arteries: The Occipital Artery
2. Veins: The External Jugular Vein
a) The Accessory Nerve (Cranial Nerve XI)
b) The Cervical Nerve Plexus
4: Lymph Nodes
What are the attachments of the Sternocleidomastoid Muscle?
Manubrium (of the Sternum) and the Clavicle
The Mastoid Process
Which way will the head tilt if the ipsilateral Sternocleidomastoid muscle contracts? And which way would that cause the Face to turn?
To the ipsilateral side
(If the right Sternocleidomastoid contracts, the head tilts to the right)
Resulting in the Face turning to the Left
What are the actions of the Trapezius?
Rotates and Retracts the Scapula
Supports the Movements of the Arm
Which Nerve innervates the Sternocleidomastoid Muscle, and the Trapezius Muscle?
The Accessory Nerve (Cranial Nerve XI)
The Ventral Rami of the Lower Cervical Spinal Nerves emerge from between the Scalene Muscles which form the floor of the Posterior Triangle. What do these Rami collectively form?
The Brachial Plexus
Name the 4 Triangles the Anterior Triangle can be split up into.
1. The Submental Triangle
2. The Digastric (Submandibular) Triangle
3. The Carotid Triangle
4. The Muscular Triangle
What are the boundaries of the Submental Triangle?
Medially - The Midline
Inferiorly - The Hyoid Bone
Laterally - The Anterior Belly of the Digastric Muscle
What are the boundaries of the Digastric (Submandibular) Triangle?
Superiorly - The Body of the Mandible
Anteriorly - The Anterior Belly of the Digastric Muscle
Posteriorly - The Posterior Belly of the Digastric Muscle
What are the boundaries of the Carotid Triangle?
Superiorly - The Posterior Belly of the Digastric Muscle
Inferiorly - The Superior Belly of the Omohyoid
Laterally - The Anterior border of the Sternocleidomastoid Muscle
