Assessing Neck Flashcards
Area of the neck are defined by the ____, which divide each side of the neck into 2 triangles: the anterior and posterior
sternocleidomastoid muscles
Each sternocleidomastoid muscle extends from the
Upper sternum and the medial third of the clavicle to the mastoid process of the temporal bone behind the ear
Each trapezius muscle extends
from the occipital bone of the skull to the lateral third of the clavicle
These muscles turn and laterally flex the head
Rotates and flexes the head
sternocleidomastoid muscles
These muscles draw the head to the side and back, elevate the chin, and elevate the shoulders to shrug them
Extend the head and moves the shoulders
Trapezius muscles
Lymph nodes in the neck that collect lymph from the head and neck structures are grouped serially and referred to as __
Chains
● Small bean-shaped organs of lymphatic
system
● Linked by lymphatic vessels
● Filters lymphatic fluid
● Major sites of lymphocytes
● Body contains hundreds of it

Anterior and posterior triangle
are two of the paired muscles that allow movement and provide support to the head and neck (Fig. 15-3).
The sternomastoid (sternocleidomastoid) and trapezius muscles
The ___ nerve is responsible for muscle movement that permits shrugging of the shoulders by the trapezius muscles and turning the head against resistance by the sternomastoid muscles.
eleventh cranial
The ___ is located under the mandible, anterior to the sternomastoid muscle.
anterior triangle
The ___ is located between the trapezius and sternomastoid muscles.
posterior triangle
The ___ (C1 through C7) are located in the posterior neck and support the cranium.
cervical vertebrae
filter lymph, a clear substance composed mostly of excess tissue fluid, after the lymphatic vessels collect it but before it returns to the vascular system.
Filtering removes bacteria and tumor cells from lymph.
Lymph nodes
Lymph nodes produces ___ as a defense against invasion by foreign substances, assisting with the body’s immunity.
lymphocytes and antibodies
The size and shape of lymph nodes vary, but most are less than 1 cm long and are buried deep in the ___. They usually appear in clusters that vary in size from 2 to 100 individual nodes.
connective tissue
The most common head and neck lymph nodes are referred to as follows:
• Preauricular
• Postauricular
• Tonsillar
• Occipital
• Submandibular
• Submental
• Superficial cervical
• Posterior cervical
• Deep cervical
• Supraclavicular
