Anatomy Flashcards
Anatomy
Study of body structures and physical relationship between body parts.
Gross anatomy
Large structures seen with the naked eye
- surface anatomy
- regional anatomy
- systemic anatomy
- developmental anatomy
- clinical anatomy
Surface anatomy
General forms and markings
Regional anatomy
Areas of specific regions
Example:head, trunk etc.
Systemic anatomy
Regards specific organ systems
Example: nervous,endocrine etc
Developmental anatomy
Embryological development of body parts
Clinical anatomy
From perspective of medical subspecialty
Ex: radiographic, surgical etc
Microscopic anatomy
Structures seen only with magnification
Ex: cytology, histology
Cytology
Study of cells
Histology
Study of tissue
Anatomical Position
Facing forward with sole of feet down and palms forwards
Anatomical sections
Sagittal
Coronal
Transverse
Sagittal sections
Vertically divides body into left and right halves
Mid-sagittal
Para-sagittal
Mid-sagittal
Divided in equal halves
Para-sagittal
Divided unequally
Coronal (frontal) sections
Vertically divides the body into anterior/Ventral and posterior/dorsal
Transverse (cross-sectional)
Horizontally divides into superior/cranial and inferior/caudal
Body cavities
Dorsal body cavity
Ventral body cavity
Dorsal body cavity
Lined with meninges
Cranial cavity: houses brain and brainstem
Spinal cavity: houses the spinal cord
Ventral body cavity
Contains viscera lined with serosal membranes to avoid adhesion
Thoracic cavity
Abdominopelvic Cavity
Thoracic Cavity
In torso and superior to diaphragm
Left & right pleura houses lungs which are encased in pleural membrane
Mediastinum between pleura & houses heart in pericardial sac
Abdominopelvic Cavity
Region of torso below the diaphragm
Quadrants-vertical from midline and horizontal from umbilicus
Quadrants
Right upper- houses liver and gallbladder
Left upper- stomach, spleen, and pancreas
Right lower- houses appendix
Abdominopelvic region
Midclavicular and angle ribs no top of ilium
Right & left hypochondriac Epigastric Right & left lumbar Umbilicus Right & left iliac Pubic
General regional devision
Abdominal region-above pelvic bones
Perotoneal membrane-serosal membrane encasing viscera
Retroperitoneal viscera-viscera are behind peritoneum,anchored w/Ct
Pelvic region
Within the bones of the pelvic cavity
