The atlas of human body

Nose
Nose

A specialized structure that serves as an organ of the sense of smell as well as part of the respiratory system; the term includes both the external nose and the nasal cavity.

Laryngeal Cartilages
Laryngeal Cartilages

The nine cartilages of the larynx, including the cricoid, thyroid and epiglottic, and two each of arytenoid, corniculate and cuneiform.

Epiglottis
Epiglottis

Thin leaf-shaped cartilage, covered with mucous membrane, at the root of the tongue, which folds back over the entrance to the larynx, covering it, during the act of swallowing.

Arytenoid Cartilage
Arytenoid Cartilage

One of a pair of small pyramidal cartilages that articulate with the lamina of the cricoid cartilage. The corresponding vocal ligament and several muscles are attached to it.

Cricoid Cartilage
Cricoid Cartilage

The small thick cartilage that forms the lower and posterior parts of the laryngeal wall.

Thyroid Cartilage
Thyroid Cartilage

The largest cartilage of the larynx consisting of two laminae fusing anteriorly at an acute angle in the midline of the neck. The point of fusion forms a subcutaneous projection known as the Adam's apple.

Nasal Septum
Nasal Septum

The partition separating the two nasal cavities in the midplane, composed of cartilaginous, membranous and bony parts.

Pharyngeal Muscles
Pharyngeal Muscles

The muscles of the pharynx are the inferior, middle and superior constrictors, salpingopharyngeus, and stylopharyngeus.

Esophageal Sphincter, Upper
Esophageal Sphincter, Upper

The structure at the pharyngoesophageal junction consisting chiefly of the cricopharyngeus muscle. It normally occludes the lumen of the ESOPHAGUS, except during SWALLOWING.

Laryngeal Muscles
Laryngeal Muscles

The intrinsic muscles of the larynx are the aryepiglottic(us), arytenoid(eus), cricoarytenoid(eus), cricothyroid(eus), thyroarytenoid(eus), thyroepiglottic(us) and vocal(is).

Turbinates
Turbinates

The scroll-like bony plates with curved margins on the lateral wall of the nasal cavity.

Nasal Bone
Nasal Bone

Either of two small elongated rectangular bones that together form the bridge of the nose.

Goblet Cells
Goblet Cells

A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.

Pharynx
Pharynx

A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).

Respiratory System
Respiratory System

The tubular and cavernous organs and structures, by means of which pulmonary ventilation and gas exchange between ambient air and the blood are brought about.

Larynx
Larynx

An irregularly shaped, musculocartilaginous tubular structure, lined with mucous membrane, located at the top of the trachea and below the root of the tongue and the hyoid bone. It is the essential sphincter guarding the entrance into the trachea and functioning secondarily as the organ of voice.

Glottis
Glottis

The vocal apparatus of the larynx, consisting of the true vocal cords (plica vocalis) and the opening between them (rima glottidis).

Vocal Cords
Vocal Cords

The folds of mucous membrane along either wall of the larynx from the angle between the laminae of the thyroid cartilage to the vocal process of the arytenoid cartilage.

Lung
Lung

Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.

Bronchi
Bronchi

The larger air passages of the lungs arising from the terminal bifurcation of the trachea.
