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 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.
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen. They are arranged as an inner layer of longitudinal muscles and an outer circular layer.
