Study Notes
Integumentary System
- Synonyms for integumentary system are integument, skin, and cutaneous membrane.
- Functions include protection from damage (mechanical, chemical, thermal, bacterial, UV radiation, desiccation), body temperature regulation (heat loss/retention), excretion (urea, uric acid), and Vitamin D synthesis.
- Skin structure includes epidermis (outermost, stratified squamous epithelium), dermis (dense connective tissue, hair follicles, sweat glands), and subcutaneous tissue (hypodermis, fat storage, anchors skin).
Epidermis Layers
- Stratum basale (germinativum): bottom layer, basal cells.
- Stratum spinosum: above basale, keratin production.
- Stratum granulosum: loses nucleus, keratin builds up.
- Stratum lucidum: present in thick skin (palms/soles).
- Stratum corneum (corneocytes): outermost, dead cells, keratin, barrier.
Dermis Cells
- Keratinocytes: most common skin cells, produce keratin (strength).
- Melanocytes: produce melanin (skin color).
- Dendritic cells: pathogen recognition, immune response.
- Tactile (Merkel) cells: light touch sensation.
Skin Appendages
- Cutaneous glands: exocrine glands (sebaceous, sweat), secrete oils/moisture, regulate skin conditions.
- Sebaceous glands: secrete sebum (oils).
- Sweat glands: produce sweat (water, salt, waste).
Skin Homeostatic Imbalances
- Burns: tissue damage from heat, electricity, UV, or chemicals.
- Infections: Athlete's foot (tinea pedis), boils, carbuncles, cold sores, and impetigo.
- Allergies.
Skin Cancer
- Causes include mutations, chemicals, physical trauma.
- Types include basal cell carcinoma (common, least malignant).
- Squamous cell carcinoma (scalp, dorsum, lower lip), malignant melanoma (melanocytes, spreading).
Skeletal System
- 206 bones in adults (300 in babies), support and structure.
- Axial skeleton: skull, vertebral column, rib cage.
- Appendicular skeleton: limbs, pectoral/pelvic girdles.
- Bone types: long, short, flat, irregular.
- Bone functions: support, protection, movement, hematopoiesis.
- Bone formation: intramembranous (skull) and endochondral (majority).
Bone Structures
- Projections and processes: attachment sites for muscles, ligaments.
- Depressions and hollows: articulations, passageways for blood vessels, nerves.
- Condyle, crest, epicondyle, foramen and fossa are all features related to bone.
Skull Structure
- Two main groups: cranial (skull) and facial bones.
- Cranial bones: frontal, parietal, occipital, temporal, sphenoid, ethmoid.
- Facial bones: support facial features and structures.
- Fontanels are membrane connecting incomplete skull bones in infants.
- Ear ossicles: malleus, incus, stapes (smallest bones).
Spinal Column
- Cervical, thoracic, lumbar, sacrum, coccyx.
- Vertebrae structures and functions.
- Ribs connect to the thoracic vertebrae.
Hip Bones
- Formed by ilium, ischium, pubis.
- Part of the pelvic girdle.
Joints
- Connective tissue joining bones.
- Types: fibrous, cartilaginous, synovial.
- Synovial joints are the most freely movable types—they're covered by cartilage and fluid.
- Common illnesses related to joints include arthritis.
Muscular System
- Muscle tissue types: skeletal (attached to bones, voluntary), smooth (internal organs, involuntary), cardiac (heart, involuntary).
- Muscle functions: movement, posture, heat production.
- Muscle cell/muscle fibers and their functions.
- Prime mover, synergists and antagonists are muscle groups responsible for movement.
Muscle Tissue Characteristics
- Excitability: receive and respond to stimuli.
- Contractility: shorten and thicken.
- Extensibility: lengthen.
- Elasticity: return to resting length.
Energy Production in Muscles
- ATP (adenosine triphosphate): chemical energy for muscle contractions.
- Creatine phosphate, aerobic respiration, and lactic acid production are three ways muscles make ATP to perform muscle contraction.
Body Movements
- Flexion, extension, hyperextension, dorsiflexion, plantar flexion, abduction, and adduction.
- Muscle groups that perform these movements.
