Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes.
The cricotracheal ligament connects (the inferior border of) the cricoid cartilage superiorly, and the first tracheal cartilage ring inferiorly. It is continuous with the tracheal perichondrium [1] and resembles the fibrous membrane which connects the cartilaginous rings of the trachea to each other. [citation needed]
Anatomy [ edit ] The anterior longitudinal ligament extends superoinferiorly between the basiocciput of the skull and the anterior tubercle of the atlas (cervical certebra C1) superiorly, and the superior part of the sacrum inferiorly; [ 1 ] inferiorly, it ends at the sacral promontory . [ 2 ]
The anterior portion of the disc attaches inferiorly to the anterior condyle and superiorly to the eminence by bending with the joint capsule. Posteriorly, the disc attaches superiorly to the temporal bone and inferiorly to the posterior condyle (the posterior attachments are frequently called the bilaminar zone).
The external oblique, closest to the surface, extend inferiorly and medially, in the direction of sliding one’s four fingers into pants pockets. Perpendicular to it is the intermediate internal oblique, extending superiorly and medially, the direction the thumbs usually go when the other fingers are in the pants pocket. The deep muscle, the ...
Superiorly, the retropharyngeal space terminates at the base of the skull (more specifically, at the clivus [2]). [1] [5] Inferiorly, the true RPS terminates at a variable level along the upper thoracic spine with the fusion of alar fascia and visceral fascia; [1] sources either give the inferior termination of the true RPS as occurring at approximately the vertebral level of T4 [2] or at a ...
The standard anatomical position, or standard anatomical model, is the scientifically agreed upon reference position for anatomical location terms.Standard anatomical positions are used to standardise the position of appendages of animals with respect to the main body of the organism.
