Document Summary
Histology: microscopic anatomy, study of tissues, tissues organs. Gross anatomy: anatomy that can be analyzed with the naked eye. Systematic anatomy: textbook has individual chapters on different systems. Regional anatomy: textbook has chapters divided into different regions of the body (thorax, head, etc. Frontal or coronal: front and back portion, silhouette of 2d plane. Transverse or horizontal or cross sectional: looking from top, upper and lower portion. Midsagittal: side profile, left and right halves down the middle, only one plane. Parasagittal or sagittal: different side profiles, 2 halves, para = to the side. Regional nomenclature based on regions of structure of body. Anatomical position: standing forward, palms facing outward, relative position of. Median = absolute middle (nose, belly button, etc: superficial vs deep surface vs deep. Proximal vs distal (closer or farther from point of attachment) Regarding nervous system rostral vs caudal (towards top vs towards tail) Differentiation = different gene expression, defines structural and functional characteristics.
