Study Notes
Anatomy 1 Exam Review
- Anatomy is the study of body structures
- Physiology studies how the body functions
- Atoms, molecules, cells, tissues, organs, and body systems
- The study of cells is cytology, and the study of tissues is histology
- There are 11 body systems: integumentary, skeletal, muscular, lymphatic, endocrine, nervous, cardiovascular, respiratory, digestive, urinary, and reproductive
Life Processes
- Metabolism: chemical processes within the body
- Growth: increase in size, number, or space between cells
- Responsiveness: reacting to internal and external stimuli
- Movement: of organs, walking, or other actions
- Differentiation: specialized cells
- Reproduction: cells or new organisms
Noninvasive Diagnostic Techniques
- Inspection: looking into the mouth or ears
- Palpation: pushing on the stomach
- Auscultation: listening to the heart or lungs
- Percussion: tapping body parts to listen for sounds
Body Planes
- Supine: lying down face up
- Prone: lying down face down
- Sagittal: divides right and left sections
- Coronal: divides anterior and posterior
- Transverse: divides upper and lower portions
- Oblique: divides at an angle
Body Cavities
- Dorsal cavity: cranial and vertebral cavities
- Ventral cavity: thoracic and abdominopelvic cavities
- Parietal layers: walls of cavities
- Visceral layers: cover internal organs
Other Anatomical Terms
- Hallux: big toe
- Pollex: thumb
- Mesenteries: hold organs in place
- Popliteal region: behind the knee
- Antecubital region: forearm (blood draw area)
- Cubital/Brachial: elbow/arm area
Cells and Tissues
- Histology: study of cells and how they become tissues
- Cells become tissues
Tissues
- Epithelial, connective, muscle, and nervous tissues
- Cell junctions: tight, adhering, gap, desmosomes, and hemidesmosomes
Epithelial Tissue
- Avascular, tightly packed
- Surface and granular types
- Simple or stratified
- Squamous, cuboidal, or columnar shapes
- Transitional epithelium: flexible
- Microvilli and cilia to increase surface area and absorption
- Keratinized and non-keratinized stratified squamous epithelium
Connective Tissue
- Present throughout the body, supporting and connecting other tissues
- Cells with extracellular matrix and highly vascularized
- Dense, loose, elastic, adipose, bone, cartilage, blood, and lymph types
Glands
- Composed of epithelial tissue
- Endocrine and exocrine glands, with differences in duct presence and hormone secretion.
Integumentary System
- Includes skin, hair, nails, cutaneous and subcutaneous layers
- Function: protection, vitamin D production, temperature regulation, excretion, sensory reception
- Epidermis (4 or 5 layers, including stratum corneum, lucidum, granulosum, spinosum, basale) and dermis (dense fibrous connective tissue)
Skeletal System
- Axial and appendicular divisions
- Bone types: flat, irregular, long, short, sesamoid, pneumatized, and sutural. Locations of specific structures such as sutures, foramen, and condyles
- Bone formation: intramembranous ossification and endochondral ossification
- Bones are made of spongy and compact bone, with red and yellow bone marrow
Other Important anatomical features
- Cranial, facial, vertebral columns
