Section 1 - Importance of anatomy
Section 2- Organization of the human body & anatomical nomenclature
⚫ Organization of the human body
➢ Chemical
➢ Cellular
➢ Tissue : similar cells that perform specialized functions
➢ Organ: 2+ tissues that work together to perform complex functions
➢ Organ system : related organs that work together to coordinate activities and achieve a common function
➢ Organism
⚫ Body divisions
➢ Axial (along the midline) : region that forms the main vertical axis of the body ; includes head, neck, trunk
➢ Appendicular (away from the midline): include the limbs or appendages attached to the axis
⚫ Organ systems
➢ Integumentary : body covering including skin and associated structures; hair, nails
➢ Skeletal: bones and joints
➢ Muscular: muscles - works with skeletal system for movement and support
➢ Nervous: brain, spinal cord, nerves
➢ Endocrine: glands that produce and secrete hormones
➢ Digestive: starts at mouth, ends at the anus
➢ Respiratory: nose, air passageways, lungs
➢ Cardiovascular system: blood, blood vessels, heart
➢ Lymphatic: lymphatic vessels, cells, structures that initiate an immune response
➢ Urinary: kidneys, ureters, bladder, urethra
➢ Reproductive
➢ Proximal/Distal
• Closer to or farther away from the origin
➢ Superficial/Deep
• Superficial: external layer of the skin
• Deep: farther from the surface of the body
➢ Parietal/Visceral
• Parietal: component of the body walls -may include muscles, connective tissue, tissue covering the organs
• Visceral: lines the outer surfaces of organs (viscera) located within the cavities
⚫ Planes and sections of the body
➢ Sagittal plane : vertical place dividing body into left and right parts
Midsagittal plane: sagittal plane passes through midline of the body
➢ Coronal: divides body into anterior and posterior parts
➢ Horizontal (transverse) : divides body into superior and inferior parts
➢ Oblique : plane that passes through body at an angle
ANAT100 Page 3
, ➢ Longitudinal: any plane perpendicular to the horizontal planes. Ex; sagittal and coronal plane
Section 3: Basic tissue- Epithelium
⚫ 4 basic types of tissue
➢ Epithelial : closely positioned cells with little or no intervening intercellular distance
• Two types
○ Covering epithelium: cells that cover the external and internal surfaces
○ Glandular epithelium: cells that produce and secrete product (ex, hormones)
➢ Connective
➢ Nervous
➢ Muscular
⚫ Characteristics of epithelium
➢ Cellularity : adjacent epithelial cells are joined by specialized junctions; tight junctions, adhering junctions, desmosomes or gap junctions
➢ Polarity: epithelial cells have an (1) exposed surface/apical facing the exterior of the body or internal space and (2) basal surface attached to th
underlying tissue
➢ Attachment : epithelial cells are attached to the basement membrane/basal lamina
➢ Avascularity: no direct contact with blood vessels -receive nutrients from blood vessels in the underlying tissue
➢ Regeneration: epithelial cells renewed continuously
⚫ Functions of epithelium
➢ Support and protection
• Covers and lines external and internal surfaces of the body protecting the underlying tissue from injury, pathogens and dehyd ration
➢ Permeability
• Allows substances to be absorbed in the body
➢ Sensation
• Some epithelial tissue contain specialized cells able to detect sensory stimuli
➢ Secretion
• Some specialized to secrete specific substances
○ Ex, skin secretes lubricating oil, enzymes & hormones secreted by digestive system
⚫ Classifying epithelium
➢ Classification based on its cell organization or cell shape
• Cell organization (# cell layers)
○ Simple : one cell layer thick
○ Stratified : 2+ cell layers thick
• Cell shape
○ Squamous : flat (thin), wide, somewhat irregular
○ Cuboidal : same size on all sides, nucleus centrally located
○ Columnar : more tall than wide- nucleus is oval and located in the basal region of the cell
