Study Notes
Definition of Anatomy
- Anatomy examines the structure of the body, including organs, tissues, bones, and cells.
- Related discipline, Physiology, studies functions of living organisms, interlinked with anatomy for understanding body functions.
Divisions of Anatomy
-
Gross Anatomy (Macroscopic): Analyzes structures without microscopy.
- Regional Anatomy: Focuses on specific body regions.
- Systemic Anatomy: Studies specific body systems.
- Surface Anatomy: Examines the body surface.
- Comparative Anatomy: Compares anatomical features across different species.
- Developmental Anatomy: Observes structural changes from fertilization to adulthood.
- Embryology: Studies structural changes up to the eighth week of development.
-
Microscopic Anatomy: Investigates structures at a cellular level.
- Histology: Study of tissues.
- Cytology: Study of cells.
- Microscopes utilized include light microscopes, electron microscopes, fluorescence, and confocal microscopes.
Characteristics of the Human Body
- Organization: Complexity in structure and function.
- Metabolism: Encompasses all body chemical reactions (anabolic and catabolic).
- Responsiveness and Movement: Cells and organs respond and move.
- Homeostasis: Stable internal environment maintained.
- Development: Growth through increased cell size and number.
- Differentiation: Cells specialize from an unspecialized state.
- Reproduction: Produces new individuals.
- Evolution: Genetic population changes over time.
Levels of Organization
- Atoms
- Molecules
- Organelles
- Cells
- Tissues
- Organs
- Organ Systems
- Organism
Organ Systems
-
Integumentary System: Comprises skin, hair, sweat glands, and nails.
- Functions include protecting from hazards, regulating temperature, providing sensory information, and Vitamin D production.
-
Skeletal System: Includes bones, cartilages, ligaments, and bone marrow.
- Functions involve support, protection, movement framework, mineral storage, and blood cell formation.
-
Muscular System: Mainly contains skeletal muscles and tendons.
- Functions are providing movement, protection, support, and heat generation.
-
Nervous System: Comprises the brain, spinal cord, peripheral nerves, and sense organs.
- Provides sensory information interpretation, directs responses to stimuli, and coordinates organ system activities.
-
Endocrine System: Includes glands such as the pituitary, thyroid, adrenal, and pancreas.
- Directs long-term activity changes in organ systems, adjusts metabolic activity and energy use.
