Study Notes

Preface

Understanding anatomy, physiology, and pathophysiology is crucial for medical technologists.
This knowledge is fundamental for informed decisions in diagnostics, procedures, and treatment.
Effective medical interventions are based on a solid understanding of the human body's structure and function.

The document contains lecture notes and laboratory manuals.
Topics covered include the human organism, chemical basis of life, cell structures, tissues, integumentary system, skeletal system, muscular system, and more.
Various laboratory manuals are included with specific page numbers.

Chapter 1: Human Organism

Chemistry is the study of the structure of the body.
Anatomy covers dissection or separation of the body.
Systemic anatomy studies the body by organ systems.
Regional anatomy studies areas of the body.
Surface anatomy is the study of external to locate internal features.
Anatomical imaging is non-invasive; examples include X-ray, CT scan, PET scan, and MRI.
Physiology studies body processes and functions.

Chapter 2: Chemical Basis of Life

Matter occupies space and has mass
Atomic structure includes neutrons, protons, and electrons.
Chemical bonding involves electron transfer or sharing, forming ionic or covalent bonds.
Polar covalent bonds involve unequal electron sharing, forming polar molecules.
Nonpolar covalent bonds have equal electron sharing, forming nonpolar molecules.
Hydrogen bonds are weak attractions.

Chapter 3: Cell Structures and Their Functions

The cell is the basic unit of life.
Cells are composed of the Plasma membrane, Cytoplasm, and Nucleus.
Plasma membrane is a barrier separating interior from the extracellular space.
Cytoplasm is the site of many metabolic processes.
Nucleus houses most of the DNA.

Chapter 4: Tissues

Tissues are groups of similar cells performing similar functions.
Epithelial tissue covers surfaces and forms glands.
Connective tissue is supporting tissue.
Muscle tissue allows movement in the body.
Nervous tissue conducts nerve impulses or action potentials.
Tissues are based on different cell shapes and structures.

Chapter 5: Integumentary System

Skin is the largest organ of the body
Epidermis - superficial layer; stratified squamous epithelium
Dermis- connective tissue (fibroblasts, macrophages, nerves, hair follicles, glands)
Hypodermis - subcutaneous layer (storage and fat)
Melanin - pigment; influences skin color
Skin receptors are for touch, pain, temp.
Accessory structures include hair, glands, and nails.

Chapter 6: Skeletal System

Skeletal system: bones, cartilage, tendons, & ligaments.
Functions include support, protection, movement, and mineral storage.
Bone is connective tissue composed of collagen, minerals, and osteocytes.
Categories of bones include: long, short, flat, and irregular.
Bone tissue layers include periosteum and endosteum.
Bone formation (ossification) occurs both intramembranous and endochondral.
Bone remodeling involves the removal and deposition of bone tissue.
Bone growth is significant in childhood and adolescence.

Chapter 7: Muscular System

Muscles allow for movement in the body.
Types of muscle include skeletal, cardiac, and smooth.
Functional characteristics include contractility, excitability, extensibility, and elasticity.
Skeletal muscles are attached to bones and enable movement.
Microscopic structure includes actin and myosin myofilaments, organized into sarcomeres.
Muscle fiber contraction occurs via the Sliding Filament Model.

Chapter 8: Nervous System

The nervous system is responsible for controlling bodily functions and integrating information.
It's made of cells called neurons which transmit action potentials; neurons and glial cells.
Neuronal pathways use converging and diverging pathways.
The spinal cord is a major pathway for signals travelling from and to the brain.
Cranial nerves connect the brain with organs.
The nervous system has different functional divisions.

Chapter 9: Senses

General senses
Specialized senses
Transduction – converting stimuli into nerve signals
Mechanoreceptors
Thermoreceptors
Photoreceptors
Chemoreceptors
Nociceptors
Pathways specific for each sense.
Specialized parts of eyes and ears.

Chapter 10: Endocrine System

Endocrine system is a chemical communication system.
Hormones have diverse chemical natures and mechanisms.
Endocrine glands produce hormones which are released to have target effects on other tissues.
Main glands and their hormones are covered.

Chapter 11: Blood

Composition of the blood includes plasma and formed elements.
Plasma is the liquid matrix, containing proteins and other solutes.
Formed elements include red blood cells, white blood cells, and platelets.
Important functions include transport of substances, regulation of pH, and clotting.
Blood typing and cross-matching are essential processes before transfusions.

Chapter 12: Heart

The heart is a muscular pump circulating blood throughout the body.
Anatomy and histology of the heart including the external and internal structures, valves, pathways, and major vessel connections.

Chapter 13: Blood Vessels and Circulation

Blood vessels form a closed network transporting blood throughout the body.
Types of blood vessels include arteries, arterioles, capillaries, venules, and veins.
Blood vessel layers and their functions are discussed.
Blood pressure is an essential measure of blood flow.

Chapter 14: Lymphatic System and Immunity

The lymphatic system plays a crucial role in immune function & fluid drainage.
Lymphatic organs, lymphatic vessels & lymph are discussed along with nonspecific resistance to explain immune processes.
Innate and adaptive immune responses are covered.

Chapter 15: Respiratory System

Gas exchange is a critical function of the respiratory system.
Anatomy includes the nose, pharynx, larynx, trachea, bronchial tree, & lungs.
Breathing mechanisms, respiratory volumes, and capacities are described.

Chapter 16: Digestive System

Digestion is an essential process for nutrient absorption and elimination of waste.
Organs, including the oral cavity, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs, are covered in regard to their anatomy, histology and physiological roles.
