Study Notes

Anatomy & Physiology Study Notes

Anatomy is the study of the structure of the body.
Physiology is the study of the function of the body.
Most medical terminology derives from Greek and Latin roots.
The textbook provides a lexicon of biomedical word elements.
Word parts include roots, combining vowels, prefixes and suffixes.
Roots carry the core meaning of a word.
Combining vowels join roots for easier pronunciation.
Prefixes modify the core meaning of a word.
Suffixes can also modify the core meaning of a word.
Misspelling can lead to confusion when referring to body parts.
Anatomical position is used as a reference point for describing body structures.
The body is divided into three planes: Sagittal, Frontal, and Transverse.
Sagittal plane divides the body into left and right segments.
Frontal (Coronal) plane divides the body into anterior and posterior segments.
Transverse (Horizontal) plane divides the body into superior and inferior segments.
Directional terms are used to describe the relative positions of body structures.
The body is divided into two major regions: axial and appendicular.
The axial region contains the head, neck and trunk (thorax and abdomen).
The appendicular region contains the upper and lower limbs.
The body contains several cavities lined with membranes and containing viscera (internal organs).
The thoracic cavity contains the lungs, heart, major blood vessels, esophagus, trachea, and bronchi.
Pleural cavities are lined with pleura.
The mediastinum separates the lungs in the thoracic cavity.
Pericardium encloses the heart.
The abdominopelvic cavity contains the digestive organs, spleen, kidneys, ureters, rectum, urinary bladder, urethra, and reproductive organs.
The abdominopelvic cavity is separated by the brim of the pelvis.
The peritoneum is a 2-layered serous membrane lining the abdominopelvic cavity.
Histology is the study of tissues.
Tissues are preserved, sliced, and sectioned for examination.
Sections are sliced into thin sections 1-2 cells thick.
Stains are used to provide contrast between tissues or cell components.
Longitudinal section cuts along the long axis.
Cross/Transverse section cuts perpendicular to the long axis.
Oblique section cuts at an angle between the longitudinal and transverse planes.
Epithelial tissue is characterized by tightly packed cells with little extracellular matrix.
Simple squamous epithelium is a single layer of flat cells, involved in absorption, secretion and movement of mucous. It is found in the lining of blood vessels, alveoli, and Bowman's capsule in the kidney.
Simple cuboidal epithelium is a single layer of cube-shaped cells, with a central nucleus. It is involved in absorption, secretion of mucous, and is found in glands and tubules of the kidney.
Simple columnar epithelium is a single layer of tall, rectangular cells with a nucleus towards the basal portion of the cell. It has microvilli and may contain goblet cells. This epithelium is involved in absorption, secretion, and the movement of mucous. It is present in the lining of the digestive tract, uterus, kidney tubules, and uterine tubes.
Stratified squamous epithelium has multiple layers of cells with a squamous shape on the surface. It can be keratinized or nonkeratinized. This epithelium is resistant to friction and penetration of pathogens. It is present in the epidermis of the skin, palms, soles, tongue, oral mucosa, esophagus, and vagina.
Stratified cuboidal epithelium has two or more layers of cube-shaped cells. It is involved in secretion. It is found in ducts of sweat glands, ovarian follicles, and seminiferous tubules.
Connective tissue is the most abundant, distributed, and highly variable tissue in the body.
It is characterized by cells that occupy less space than the matrix they secrete.
Connective tissue functions include binding organs, support, physical protection, immune protection, movement, storage, heat production, and transport.
Fibrous connective tissue is divided into loose and dense connective tissue.
Loose connective tissue contains more ground substance than cells and fibers. It is found under epithelial tissue and surrounding organs.
Dense connective tissue contains more fibers than cells and ground substance. It can be regular or irregular.
Dense regular connective tissue, like tendons and ligaments, has fibers running in a parallel arrangement.
Dense irregular connective tissue, like the dermis, has irregularly arranged fibers.
Adipose tissue is a type of connective tissue characterized by adipocytes, cells that store fat.
It is found under the skin and surrounds organs.
White fat serves as the body's primary energy reservoir, provides thermal insulation, and cushions organs.
