BIO 1105 Lecture Notes - Lecture 8: Sagittal Plane, Transverse Plane, Cervical Vertebrae
Document Summary
Vertebrae anatomy- external features and skeletal system of the rat. Proximal: toward the end of the appendage nearest the body. Lateral: away from the midline of the body; toward the side. Distal: toward the end of an appendage farthest away from the body. Frontal plane: divides the body into dorsal and ventral halves; two dimensional plane parallel to the anterior posterior axis and perpendicular to the dorsal-ventral axis. Transverse plane: a cross section; two dimensional plane perpendicular to the anterior-posterior axis of the body. Sagittal plane: divides the body into left and right halves; two dimensional plane parallel to the anterior- posterior axis and parallel to the dorsal ventral axis. Rat"s body is divided into 6 anatomical regions: Vibrissae: tactilely (relative to touch) sensitive whiskers on the face. Nares: nostrils at the anterior end of the head. Subterminal mouth: has a cleft in the upper lip that exposes incisors: large front teeth.
