| Term | Definition |
|---|---|
| Otoscope | is an instrument used to examine the ear canal and eardrum |
| Structures of the Ear | Ear Canal Tympanic Membrane Ossicles Eustachian Tube Cochlea Semicircular Canals |
| Ear Canal | a tube-like structure that connects the outer ear to the middle ear |
| Tympanic Membrane | is a thin, semitransparent membrane that separates the external ear from the middle ear |
| Ossicles | three tiny bones in the middle ear that amplify and transmit sound vibrations from the eardrum to the inner ear |
| Eustachian Tube | an opening that connects the middle ear with the nasal-sinus cavity |
| Cochlea | a spiral-shaped organ in the inner ear that converts sound waves into electrical impulses that the brain can interpret as soun |
| Semicircular Canals | three fluid-filled tubes in the inner ear that help you sense head movement and maintain balance |
| Acute Otitis Media | known as an ear infection, is an inflammation of the middle ear that causes pain, discomfort, and hearing loss. |
| Ophthalmoscope | an instrument for inspecting the retina and other parts of the eye |
| Visual Accuity | a measure of the ability of the eye to distinguish shapes and the details of objects at a given distance |
| Conjunctivitis | often called “pink eye”—is inflammation of the conjunctiva from infection or allergies |
| 4 Signs of Inflammation | Redness Swelling Heat Pain |
| Redness | when its red |
| Swelling | a condition where excess fluid accumulates in the body's tissues, causing them to become enlarged and puffy |
| Heat | the quality of being hot; high temperature |
| Pain | an unpleasant sensory and emotional experience associated with actual or potential tissue damage |
| Structures of the Oral Cavity | Tonsils Uvula Pharynx Tongue |
| Tonsils | two oval-shaped masses of lymphatic tissue located at the back of the throat, one on each side |
| Uvula | The soft flap of tissue that hangs down at the back of the mouth (at the edge of the soft palate) |
| Pharynx | a hollow, muscular tube inside the neck that starts behind the nose and opens into the larynx and esophagus |
| Tongue | a muscular organ that helps with eating, drinking, speaking, and breathing |
| Skin Cancer Screening (Mole Checks) | Asymmetry Boarder Color Diameter Evolving |
| Asymmetry | the lack of balance or proportion between parts of a thing |
| Boarder | The outer part or edge; boundary |
| Color | look at the color, if its multiple diffrent shades or colors it can be bad |
| Diameter | the size can show if it will or is a problem |
| Evolving | develop gradually, especially from a simple to a more complex form. like change of color or getting bigger |
| Malignant | It can also describe a cancerous cell or tissue |
| Melanoma | a type of skin cancer that develops from melanocytes |
| Benign | not harmful in effect |
| Auscultation | the action of listening to sounds from the heart, lungs, or other organs, typically with a stethoscope, as a part of medical diagnosis. |
| Intercostal Space | the gap between the ribs in the chest |
| Lub-Dub | the sound of a heartbeat, caused by the opening and closing of the heart's valves |
| S1 & S2 sounds | "S1" representing the first sound (often described as "lub") caused by the closure of the mitral and tricuspid valves, and "S2" representing the second sound ("dub") caused by the closure of the aortic and pulmonary valves |
| Murmur | an irregular heart sound |
| Premature Ventricular Contraction (PVC) | irregular heartbeats that originate in the ventricles (lower chambers of the heart) |
| Structures of the Heart | Aortic Valve Pulmonic Valve Tricuspid Valve Mitral Valve Aorta / Atria Ventricle(s) |
| Aortic Valve | regulates blood flow between the left ventricle (heart's main pumping chamber) and the aorta (the largest artery in the body). |
| Pulmonic Valve | a semilunar valve located in the heart that controls the flow of blood from the right ventricle to the pulmonary artery |
| Tricuspid Valve | located on the right side of the heart, between the right atrium and the right ventricle |
| Mitral Valve | one of four valves in the heart that keep blood flowing in the right direction |
| Aorta / Atria | The aorta is the body's largest artery, and the atria are the heart's upper chambers |
| Ventricle(s) | each of the two main chambers of the heart, left and right |
| Abnormal Lung Sounds | Wheezing Crackles (Rales) Rhonchi Stridor |
| Wheezing | a high-pitched, whistling sound that occurs when air flows through narrowed airways in the lungs |
| Crackles (Rales) | abnormal lung sounds that can be heard through a stethoscope. They are caused by fluid or air in the small airways of the lung |
| Rhonchi | coarse, low-pitched, rattling sounds heard in the lungs during breathing. They occur when air passes through narrowed or obstructed airways |
| Stridor | a high-pitched, whistling sound that occurs when air flows through a narrowed or obstructed airway |
| Structures of the Respiratory System | Trachea Larynx Lungs |
| Trachea | The airway that leads from the larynx (voice box) to the bronchi |
| Larynx | e hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box |
| Lungs | One of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body |
| Bronchus / Bronchi | A large airway that leads from the trachea (windpipe) to a lung. The plural of bronchus is bronchi. |
| Bronchioles | A tiny branch of air tubes in the lungs |
| Alveoli | any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange |
| Pleura | a thin, double-layered membrane that covers the lungs and lines the inside of the chest cavity |
| Diaphragm | a dome-shaped muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs. |
