Study of the STRUCTURE of the body parts and their relationship to one another
Study of the FUNCTION of the body and how these parts work
Gross Anatomy, Macroscopic Anatomy
Study of large body structures visable to the naked eye. Broken down into Regional Anatomy,Systemic Anatomy, Surface Anatomy
Regional Anatomy
All the structures in a particular region of the body
Systemic Anatomy
Body structures which are studied system by system
Surface Anatomy
The study of internal structures as they relate to the overlying skin surface
Microscopic Anatomy
The study of stuctures too small to be seen by the naked eye. Broken down into Cytology and Histology
The study of body cells
The study of body tissues
Developmental Anatomy
a study that traces structural changes that occur in the body throughout the life span
Specialized Anatomy
specialization, i.e. Radiographic anatomy which studies internal structures via x-ray, etc.
Levels of Structural Organization
Chemical - Cellular - Tissue Level - Organ - Organ System - Organismal Leval
What are the 4 types of tissue
1. Epithelium
2. Muscle
3. Connective Tissue
4. Nervous Tissue
Toward the head end or upper part of a structure of the body, above
Away from the head, below, toward the lower part of the structure or the body
Ventral or Anterior
Toward or at the front of the body; in front of
Dorsal or Posterior
Toward or at the back of the body, behind
Toward or at the midline of the body; on the inner side of
Away from the midline of the body, on the outer side of
Between a more medial and a more lateral structure
Closer to the origin of the body part or the point of attachment of a limb to the body trunk
Farther from the origin of a body part or the point of attachment of a limb to the body trunk
Superficial (external)
Toward or at the body surface
Deep (internal)
Away from the body surface, more internal
Regional Terms - what is the definition of this? What are the two fundamental divisions?
Terms used to designate specific areas within the major body divisions. The two fundamental divisions are Axial and Appendicular
that which makes up the main axis of our body. i.e. the head, neck and trunk.
The appendages or limbs which are attached to the bodies axis.
Body Planes
for anatomical studies, how the body is sectioned along a flat surface (plane)
Sagittal plane
(Arrow) a vertical plane that divides the body into right and left parts.
Median Plane
A sagittal plane that lies exactly in the midline
Parasaggital planes
Saggital planes that are offset from the midline (from para =near)
Frontal Planes, Coronal Plane
Front and back division. Frontal planes are like sagittal planes because they lie vertically, but Frontal planes divide the body into anterior and Posterior parts.
Transverse or horizontal plane
a plane that runs horizontally from right to left and divides the body into superior and inferior parts. Can be at any level from head to foot. *** Also called a cross section
Oblique Sections
Cuts made diagonally between the horizontal and vertical planes. Seldom used.
Dorsal Body Cavity
cavity that protects the fragile nervous system organs. 2 Subdivisions - A.) Cranial Cavity and B.) Vertebral or Spinal Cavitiy
Cranial Cavity
cavity that encases the skull
Vertebral Cavity
Also known as the spinal cavity. cavity that encloses the spinal cord. runs within the vertebral column.
Ventral Body Cavity
Body cavity which is anterior to the dorsal cavity and larger than the dorsal cavity. 2 Subdivisions - A.) thoracic Cavity B.) abdominopelvic cavity
Thoracic Cavity
cavity surrounded by ribs and muscles of the chest. Divided into
a.) pleural cavity (lateral)
b.) mediastinum (medial)
Medial cavity within the thoracic cavity that contains the pericardial cavity, which encloses the heart. It also surrounds the remaining thoracic organs (esophagus, trachea and others)
Abdominopelvic CAvity
Inferior to the thoracic cavity. Seperated by the diaphram. 2 parts
a.) abdominal cavity - stomach, intestines, spleen, liver and other organs
b.) pelvic cavity - bladder, some reporductive organs, and the rectum
thin, double layer membrane covering the walls of the ventral cavity and the outer surfaces of the organs it contains
Parietal serosa
part of the membrane lining the cavity walls.
(parie = wall)
visceral serosa
parietal serosa that folds in on itself. Covers the organs in the cavity
Name the tic tac toe pattern of teh abdominopelvic regions and quadrants
Right Epigastric Left
Hypo hypo
chondriac condriac

Right Umbilical Left
Lumbar Lumbar

Right Hypogastic Left
Iliac Iliac
What are the three principles of the cell theory
1.) The cell is the basic structural and functional unit of living organisms
2.) The activity of an organism depends on both the individual and the collective activities of its cells
3.) Continuity of life has a cellular basis
Plasma Membrane
Also known as the cell membrane. Enclosed the cell and seperates the intracellular fluids within the cells from the extracellular fluids outside the cell.
What is the plasma membrane composed of?
A double layer, or bilayer, of lipid molecules with protein molecules dispersed in it. Composed of Phosopholipids and glycolipids.
What is a phospholipid?
lollipop shaped "head" which is hydrophilic and is charged.
