Chapter 1 : Introduction To Anatomy, Body Plans, Body Cavities, Body Terms Flashcards
Chapter 1 Microscopic Anatomy (fine anatomy) , Cytology, and Histology
The study of body structures that cannot be seen without magnification - includes Cytology ( study of cells) and Histology (study of tissues)
Gross Anatomy (Macroscopic)
The study of body structures which are visible without the aid of magnification
Surface Anatomy
The study of shapes and markings on the body surface (morphology) and how it relates to deeper structures
Regional Anatomy
The study of superficial and internal features of the body (head, neck, or trunk)
Systemic Anatomy
The study based on the organ systems of the body one at a time ( e.g. Cardiovascular system - heart, veins, arteries, etc.)

Responsiveness
The ability for an organism to change in its environment (e.g. jerking your hand from a hot surface)
Growth and Differentiation
Organism grow and produce changes and shape in form and function over time
Metabolism
Refers to all chemical operations under way in the body
Catabolism
Anabolism
Catabolism - the breakdown of complex molecules into simple ones
Anabolism - the synthesis of complex molecules from simple ones
The Integumentary System
Organs : skin, epidermis, dermis, hair follicles, sweat glands, nails, sensory receptors, subcutaneous layer
Function : covers body surface, provides protection and heat, has glands and ducts
Skeletal System
Organs : Bones, joints, cartilage, bone marrow, ligaments
Functions : support and protect of soft tissues; mineral storage, blood cell formation

Body Plane :
Frontal (Coronal) Plane
Lies vertically ; divides body into front and back
Body Plane :
Transverse (Horizontal) Plane
Lies horizontally; divides body into top and lower portions
Body Plane :
Sagittal Plane
Lies vertically ; divides body into right and left portions
Dorsal Body Cavity
Cranial - skull (cranium, brain)
Spinal - vertebral column (spinal cord)
Ventral Cavity (Coelom)
- provides protection, organ movement, lining prevents friction
Thoracic Cavity
Superior to diaphragm - contains heart, lungs, blood vessels, surrounded by ribs and muscles of chest wall
Thoracic Cavity :
Pleural Cavities - encloses both lungs
Parietal Pleura - lines chest wall of serous membrane
Visceral Pleura - lines lungs of serous membrane
Serous Fluid - fills cavity in layers of serous membrane
Thoracic Cavity :
Mediastinum - lines the heart, esophagus, trachea, and major blood vessels
Pericardial cavity - heart
Parietal Pericardium - thin ; lines pericardial walls
Visceral Pericardium - thin; lines heart surface
Serous Fluid - fills pericardial cavity
Abdominopelvic Cavity
Lies inferior to diaphragm ; divided into superior and inferior portions
Abdominal Cavity :
Superior part contains liver, stomach, small intestine, spleen, kidneys
Parietal Peritoneum - thin ; lines wall of serous membrane
Visceral Peritoneum - thin ; lines abdominal pelvic organs
