NECK Flashcards
Occupies the region between skull and thorax.
THE NECK
The neck is divided into ______ and ______ portions.
POSTERIOR, ANTERIOR
In front portion of the neck, of the vertebrae, is composed of
SOFT TISSUES
UPPER PARTS OF THE RESPIRATORY & DIGESTIVE SYSTEM
THYROID & PARATHYROID GLAND
SUBMANDIBULAR GLAND
Consist of two lateral lobes connected together at the lowerthird by a narrow median portion called the “isthmus”.
THYROID GLAND
Thyroid Gland is consist of two lateral lobes connected together at the lowerthird by a narrow median portion called the ________.
ISTHMUS
The thyroid gland is consist of _________ connected together at the lowerthird by a narrow median portion called the “isthmus”.
TWO LATERAL LOBES
Lies at the front and sides of the upper part of the trachea.
THE LOBES
Are small ovoid bodies and are normally 4 in number- 2 on each side.
PARATHYROID GLAND
Situated only on the posterior part of the thyroid gland
PARATHYROID GLAND
Serves as the passage both air and food and is common to the respiratory and digestive systems.
PHARYNX/THROAT
It is a musculo-membranous, tubular structure situated in front of the vertebrae and behind the nose, the mouth and larynx.
PHARYNX/THROAT
Pharyngeal Cavity is subdivided into:
NASAL CAVITY
ORAL CAVITY
LARYNGEAL PORTION
It is the organ of voice
LARYNX
It serves also as the air passage between pharynx and the trachea
LARYNX
It is suspended from the hyoid bone and extends from the level of the superior margin of the 4th cervical vertebra to its junction with the trachea
LARYNX
9 Cartilages of Larynx
SINGLE: EPIGLOTTIS, THYROID CARTILAGE, CRICOID CARTILAGE
PAIRED: ARYTENOID, CORNICULATE, CUNEIFORM
A thin leaf-shaped situated behind the root of the tongue and the hyoid bone and above the laryngeal entrance.
EPIGLOTTIS
The largest of its group which forms the laryngeal prominence or the Adam’s Apple” at the level of C5
THYROID CARTILAGE
Second largest of the group and is connected to the 1st ring of the trachea
CRICOID CARTILAGE
Composition of the bone of the thorax
STERNUM/BREAST BONE
12 THORACIC VERTEBRAE
12 PAIRS OF RIBS
Is a long flattened bone from front to back that lies vertically in the anterior chest wall in the midline
STERNUM
Is the upper segment which in early life is separated from the body by cartilage but later it fuses with the body
MANUBRIUM
Is that part that extend from the manubrium to the xiphoid process
BODY OF THE STERNUM/GLADIOLUS
Is the lower pointed end below the body at the level of T10
XIPHOID/ ENSIFORM PROCESS
Is the concave upper boarder of the manubrium at the level of T2-T3
SUPRA-STERNAL/JUGULAR NOTCH
Are depressions found at each lateral border of the supra-sternal notch.
CLAVICULAR NOTCHES
CLAVICULAR notch and the medial end of the clavicle form the ______.
STERNOCLAVICULAR JOINT
Are depressions on each lateral margin of the sternum which articulate with the costal cartilages
COSTAL NOTCHES
Is the prominent transverse ridge at the junction of the manubrium and the body of the sternum at the level of T4-T5
STERNAL ANGLE/ ANGLE OF THE LEWIS
Are flat curved bones that form part of the posterior wall, the entire lateral wall and part of the anterior wall of the thorax.
RIBS
Is the slightly expanded posterior end which articulate with the pits on the adjacent border of the vertebra
