Study Notes

Gross Anatomy

Structures examined without a microscope
Regional anatomy focuses on specific body regions, highlighting relationships
Systemic anatomy examines structures related to specific systems
Histology examines microscopic structures and tissue types
Anatomical position is a standard reference point for describing body regions

Directional Terms

Superior (toward the head)
Inferior (away from the head)
Anterior (front of the body)
Posterior (back of the body)
Medial (toward the midline)
Lateral (away from the midline)
Intermediate (between two structures)
Ipsilateral (same side of the body)
Contralateral (opposite side of the body)
Proximal (nearer to point of attachment)
Distal (farther from point of attachment)
Superficial (toward the surface)
Deep (away from the surface)

Body Planes

Midsagittal (medial) plane: divides the body into equal left and right halves
Parasagittal plane: divides the body into unequal right and left halves
Frontal (coronal) plane: divides the body into anterior and posterior sections
Transverse (horizontal) plane: divides the body into superior and inferior sections

Body Cavities

Posterior body cavity: cranial cavity (skull) and vertebral (spinal) cavity
Anterior body cavity: thoracic cavity (mediastinum, pericardial cavity, pleural cavities) and abdominopelvic cavity (abdominal and pelvic cavities)

Structural Organization

Molecules, cells, tissues, organs, systems, organism
Tissues: Aggregations of similar cells and their associated materials
Organs: Structures with a specific function, composed of more than one tissue
Systems: Groups of organs working together

Types of Muscle Tissue

Skeletal muscle: Striated, voluntary, multiple nuclei per fiber, attached to skeleton (movement)
Cardiac muscle: Striated, involuntary, branched, single nucleus, in the heart (heart contraction)
Smooth muscle: Smooth, involuntary, single nucleus, in blood vessels and internal organs (organ function)

Types of Epithelial Tissue

Simple squamous epithelium: single layer of flattened cells (diffusion)
Simple cuboidal epithelium: single layer of cube-shaped cells (absorption, secretion)
Simple columnar epithelium: single layer of column-shaped cells (absorption, secretion)
Pseudostratified columnar epithelium: single layer with varying heights (secretion, movement of mucus)
Stratified squamous epithelium: multiple layers of flattened cells (protection)

Types of Connective Tissue

Hyaline cartilage: Found in the end of long bones, nose, trachea (support, flexibility)
Adipose tissue: Fat cells (insulation, protection, energy storage, cushioning)
Dense regular collagenous connective tissue: Collagen fibers arranged in parallel bundles (tensile strength, structural support)
- Tendons and ligaments
Loose connective tissue: Elastic fibers, collagen fibers (connection of organs, support)
Dense regular elastic connective tissue: elastic fibers (expansion)

Nervous Tissue

Neurons: Cells that transmit impulses (coordinate and control body functions)
Neuroglia cells: supportive cells
