This article describes the anatomy of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat.
An attempt of a map the muscles in our list of skeletal muscles graphically based on location, showing variations and parts of the same muscle as well as number of standard occuranes in the human body

The facial muscles include: Occipitofrontalis muscle; Temporoparietalis muscle; Procerus muscle; Nasalis muscle; Depressor septi nasi muscle; Orbicularis oculi muscle; Corrugator supercilii muscle; Depressor supercilii muscle; Auricular muscles (anterior, superior and posterior) Orbicularis oris muscle; Depressor anguli oris ...
The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone. Septal nasal cartilage (ie, quandrangular cartilage) Vomer bone. The lowest part of the septum is a narrow strip of bone that projects ...
46770. Anatomical terms of muscle. [ edit on Wikidata] The nasalis muscle is a sphincter -like muscle of the nose. It has a transverse part and an alar part. It compresses the nasal cartilages, and can "flare" the nostrils. It can be used to test the facial nerve (VII), which supplies it.

Each has two surfaces and four borders.
Anatomical terminology. [ edit on Wikidata] The nasal cartilages are structures within the nose that provide form and support to the nasal cavity. [1] The nasal cartilages are made up of a flexible material called hyaline cartilage (packed collagen) in the distal portion of the nose. [2] There are five individual cartilages that make up the ...
