Head and Neck Flashcards
Framework of the head is the skull; divided into 2 subsections:
the cranium and the face.
Facial bones give shape to the face: consists of __ bones
14
➢Maxilla (2)
➢Zygomative (cheek) (2)
➢Inferior conchae (2)
➢Nasal (2)
➢Palatine
➢Vomer (1)
➢Mandible (jaw) (1)
Structure located in the facial region:
➢Parotid gland
➢Mandibular salivary gland
Composed of muscles, ligament and the cervical vertebrae
The Neck
______________________ and
_________ muscles allow movement and provide
support to the head and neck.
STERNOMASTOID and Trapezius
muscles rotates and flexes the
head,
Sternocleidomastoid
muscle extends the
head and moves the shoulders.
Trapezius
The eleventh cranial nerve is responsible for muscle
movement that permits shrugging of the shoulders
by the
tapezius muscles
turning the head
against resistance by the
stemomastoid muscles.
located under the mandible, anterior to
the stenomastoid muscle.
Anterior triangle
locate between trapezius and
sternomastoid muscles.
Posterior triangle
located in the
posterior neck and support the cranium.
Cervical Vertebrae
Internal jugular veins and carotid arteries – located bilaterally, parallel
and anterior to the sternomastoid muscles.
➢It is important to avoid bilaterally compressing the carotid arteries when
assessing the neck, as bilateral compression can reduce the blood supply to
the brain.
BLOOD VESSELS
argest endocrine gland
produces thyroid hormones that increase metabolic rate
THYROID GLAND
through which air enters the lungs is composed of: C
shaped hyaline cartilage rings
TRACHEA
first upper tracheal ring, has small notch in it.
Cricoid cartilage
larger and located just above the
cricoid cartilage
Thyroid cartilage (“Adam’s apple”)
is attached to the tongue, lies above the thyroid
cartilage and under the mandible.
➢ Hyoid bone
filter lymph, a clear substance composed mostly of
excess fluids, filtering removes bacteria and tumor cells from lymph.
➢Produce lymphocytes and antibodies as a defense against invasion by
foreign substances.
➢Not palpable or they may feel like very small beads.
➢If the nodes become overwhelmed by microorganisms, as happens with
an infection they swell and become painful
➢If cancer metastasizes to the lymph nodes, they may enlarge but not
painful.
