ANA 201 Introduction to anatomy Flashcards
Anatomical position
A situation when a person standing upright feet together (toes pointing forward) hands by the side (palms of hand forward) and the face looking forward. The mouth is closed and facial expression is neutral
Supine position
When lying in anatomical position but facing upward
Prone position
When lying in anatomical position but facing downward
Median plane
Vertical plane passing longitudinally through the body and its anatomical position dividing the body into two equal halves i.e. left and right
Sagittal plane
Vertical plane passing parallel to the median plane
Coronal Plane
Vertical plane passing through the body at right angle to the median plane does dividing the body into anterior and posterior
Transverse plane
Horizontal plane passing through the body at right angle to the median and coronal plane, thus dividing the body into superior and inferior upper and lower parts
Terms used in dissections to describe the position of one structure with respect to another
Superficial, intermediate and deep
Medial
A term used to indicate that a structure is near or nearer to the median place of the body e.g. the little finger
Lateral
Stipulates the structure is farther away from the median plane E.g. the thumb
Posterior
Denotes the back surface of the body or nearer to the back
Anterior
Denotes the front surface of the body and ventral is equivalent to anterior
Inferior
Refers to a structure that is situated near the soles of the feet. Caudal pertains to the tail and is a useful directional term when referring to the tail or trunk region (used by embryologist)
