Membrane proteins: Integral, transmembrane, peripheral
Organelles: Nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, cytoskeleton
Membrane Transport
Passive transport: Diffusion, osmosis, facilitated diffusion
Active transport: Requires energy (e.g., sodium-potassium pump)
Endocytosis and exocytosis: Bulk transport mechanisms
Cytoskeleton
Microfilaments, intermediate filaments, microtubules: Provide structural support and facilitate movement
CHAPTER FOUR – Histology
Tissue Types
Epithelial tissue: Covers surfaces, lines cavities, forms glands
Connective tissue: Supports, protects, binds other tissues (bone, cartilage, blood, adipose)
Muscle tissue: Produces movement (skeletal, cardiac, smooth)
Nervous tissue: Transmits electrical signals
Functions and Characteristics
Regeneration: Epithelial and connective tissues typically regenerate well
Fibrosis: Replacement of tissue with scar tissue
CHAPTER FIVE – The Integumentary System
Skin Structure
Epidermis: Stratified squamous epithelium; layers include stratum basale, spinosum, granulosum, lucidum, corneum
Dermis: Connective tissue; papillary and reticular layers
Hypodermis: Subcutaneous fat and connective tissue
Functions
Protection, thermoregulation, Vitamin D synthesis
Accessory Structures
Hair and nails: Derived from epidermis
Glands: Sweat (eccrine, apocrine), sebaceous (oil)
CHAPTER SIX – Bones and Bone Tissue
Functions of the Skeleton
Support, protection, movement, mineral storage, blood cell formation
Bone Structure
Long bones: Diaphysis, epiphysis, medullary cavity
Bone cells: Osteoblasts (build bone), osteocytes (maintain bone), osteoclasts (break down bone)
Bone matrix: Organic (collagen), inorganic (hydroxyapatite)
Bone Formation
Intramembranous ossification: Forms flat bones
Endochondral ossification: Forms most bones from cartilage models
CHAPTER SEVEN – The Skeletal System
Overview and Classification
Axial skeleton: Skull, vertebral column, thoracic cage
Appendicular skeleton: Limbs and girdles
Major Bones and Features
Cranial and facial bones, vertebrae, ribs, sternum, pectoral and pelvic girdles, upper and lower limb bones
CHAPTER EIGHT – Articulations
Classification of Joints
Fibrous joints: Sutures, syndesmoses, gomphoses
Cartilaginous joints: Synchondroses, symphyses
Synovial joints: Most movable; features include synovial cavity, capsule, fluid, cartilage
Movements
Flexion, extension, abduction, adduction, rotation, circumduction
CHAPTER NINE – The Muscular System
Muscle Types and Functions
Skeletal muscle: Voluntary movement
Cardiac muscle: Heart contraction
Smooth muscle: Walls of hollow organs
Major Muscles
Identification and function of major muscle groups (e.g., biceps brachii, quadriceps, trapezius)
CHAPTER TEN – Muscle Tissue and Physiology
Structure of Muscle Tissue
Muscle fibers: Myofibrils, sarcomeres, actin and myosin filaments
Sarcomere: Functional unit of muscle contraction
Excitation-Contraction Coupling
Action potential triggers release of calcium, leading to muscle contraction
Equation:
Types of Muscle Contraction
Isometric (no change in length), isotonic (change in length)
CHAPTER ELEVEN – Introduction to the Nervous System and Nervous Tissue
Organization of the Nervous System
CNS: Brain and spinal cord
PNS: Cranial and spinal nerves
Neurons and Neuroglia
Neurons: Sensory, motor, interneurons; structure includes soma, axon, dendrites
Neuroglia: Support cells (astrocytes, oligodendrocytes, Schwann cells, microglia)
Electrophysiology
Resting membrane potential: (typical)
Action potential: Rapid depolarization and repolarization
CHAPTER TWELVE – The Central Nervous System

Cerebrum: Hemispheres, lobes, cortex, basal nuclei
Diencephalon: Thalamus, hypothalamus, epithalamus
Cerebellum: Coordination of movement
Brainstem: Midbrain, pons, medulla oblongata
Protection and Support
Meninges: Dura mater, arachnoid mater, pia mater
Cerebrospinal fluid (CSF): Produced by choroid plexus, circulates in ventricles
Blood-brain barrier: Selective permeability
Spinal Cord
Gray and white matter, ascending and descending tracts
Cross-sectional anatomy: dorsal, ventral, lateral horns
CHAPTER THIRTEEN – The Peripheral Nervous System
Organization
Cranial nerves: 12 pairs, each with specific sensory/motor functions
Spinal nerves: 31 pairs; dorsal and ventral roots

Additional info:
These notes are based on a final exam review sheet and cover the first fifteen chapters of a standard Anatomy & Physiology curriculum.
For each chapter, students should be able to define key terms, describe structures and functions, and apply concepts to physiological processes.
Equations and tables have been expanded for clarity and completeness.
