Studying Chapter 1 Flashcards
Anatomy
study of structure of an organism and relationships of its parts
Physiology
Study of function of living organism and their parts
Levels of Organisms
Chemical Level (least complex) Organism Level (most complex)
Chemical Level
Atoms and Molecules
Anatomical Position
Body is standing posture with arms at sides and palms face forward
Supine
Body is lying face upward
Prone
Body is lying face downward
Superior
Toward the head; upper/above
Inferior
Towards the feet; lower/below
Anterior
Front/in front of (Ventral)
Posterior
Back / in bank of (dorsal)
Ventral
Towards the belly
Dorsal
Toward the back
Medial
Toward the midline of the body
Lateral
Towards the sides of the body or away from its midline
Proximal
Toward or nearest the trunk of the body, or nearest point of origin of one of its parts
Distal
Away from or farthest from trunk or the point of origin of a body part
Superficial
Nearer the surface
Deep
Farther away from the body surface
Sagittal Plane
cut or section runs along lengthwise plane running from front to back; divides body into right and left sides
Midsagittal Plane
sagittal plane that divides body into 2 equal parts
Frontal Plane
(Coronal Plane) lengthwise plane running from side to side; divides body into anterior and posterior (front and back) planes
Transverse Plane
horizontal or crosswise plane; divides body into upper and lower portions
2 Major Body Cavities
Dorsal body cavity // ventral body cavity
Dorsal Cavities
includes space inside skull that contains the brain (cranial cavity) and space inside the spinal column (spinal cavity)
Cranial Cavity
space inside brain
Spinal Cavity
Space inside spinal column
Ventral Cavities
located in ventral position in body; thoracic cavity // pleural cavity // mediastinum // diaphragm // abdominal cavity // abdominopelvic cavity // pelvic cavity
Upper Ventral Cavities
thoracic cavity (chest cavity)
Mediastinum
midportion of the thoracic cavity
Pleural Cavities
lateral subdivisions of the thoracic cavity (left and right)
lower ventral cavities
abdominal cavity // pelvic cavity
abdominopelvic cavity
abdominal cavity and the pelvic cavity since nothing separates the 2 cavities
Diaphragm
muscular sheet that separates the thoracic cavity from the abdominopelvic cavity
body cavities (from top to bottom)
cranial cavity - spinal cavity - thoracic cavity - pleural cavities (left and right) - mediastinum - diaphragm - abdominal cavity - abdominopelvic cavity - pelvic cavity
