Supra-
Supra
Above
Supraglottal
The supraglottis is the part of the larynx above the true vocal cords. The supraglottis itself can be broken down into 4 regions.
The epiglottis (either above or below the hyoid bone): The epiglottis is a flap of cartilage in the throat that prevents food from entering the trachea, or windpipe. This flap closes during swallowing, forcing food down the esophagus and into the stomach.
The aryepiglottic folds: The aryepiglottic folds are folds in the lining (mucosa) of the larynx that connect the epiglottis and the arytenoids at the entrance of the airway.
The arytenoids: The arytenoids are a pair of pyramid-shaped pieces of cartilage that form part of the larynx. They help form a joint that allows the vocal cords to move, and are therefore involved in speech.
The false vocal cords: The false vocal cords are thick folds of mucous membrane just above the true vocal cords. They function as an added layer of protection for the vocal cords and the airway while swallowing.
suprarenal
Adrenal glands, also known as suprarenal glands, are small, triangular-shaped glands located on top of both kidneys.
Tempor
Relating to the temple areas of the head
Temporomandibular
The temporomandibular joints (TMJ) are the 2 joints that connect your lower jaw to your skull. More specifically, they are the joints that slide and rotate in front of each ear, and consist of the mandible (the lower jaw) and the temporal bone (the side and base of the skull).
Temporal
Pertaining to the temple region of the head. The temporal lobe of the brain is located beneath the temple.
Thora-
Chest area
Thoracic
What is the thoracic area?
The thoracic spine is located in the upper and middle part of the back. Twelve vertebrae are located in the thoracic spine and are numbered T-1 to T-12. Each number corresponds with the nerves in that section of the spinal cord: T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles.
Thoracentesis
A procedure that is performed to remove fluid or air from the thoracic cavity for both diagnostic and/or therapeutic purposes. [1][2] Thoracentesis is also known as thoracocentesis, pleural tap, needle thoracostomy, or needle decompression.
Tracheo-
Relating to the trachea (windpipe)
Tracheostomy
A procedure to help air and oxygen reach the lungs by creating an opening into the trachea (windpipe) from outside the neck. A person with a tracheostomy breathes through a tracheostomy tube inserted in the opening.
Ure/i- or urethr-
Relating to the urine and the urinary tract (from the constituent of urine, urea).
Urethritis
When the tube that carries pee from the bladder out of the body (urethra) becomes swollen and sore. It’s often caused by a sexually transmitted infection (STI).
Urinary
Your urinary system includes the kidneys, ureters, bladder and urethra. The urinary system removes waste from the body through urine.
Ureter
The ureters are bilateral thin (3 to 4 mm) tubular structures that connect the kidneys to the urinary bladder, transporting urine from the renal pelvis into the bladder. The muscular layers are responsible for the peristaltic activity that the ureter uses to move the urine from the kidneys to the bladder.
-al or -ar
Pertaining to.
Renal - Relating to the kidneys
Lingual
Relating to, near, or on the side towards the tongue.
Relating to speech or language.
Lumbar
The lower back comprises the lumbar spine, which is formed by vertebral bones, intervertebral discs, nerves, muscles, ligaments, and blood vessels.
-Able or -ible
Is capable of.
Flexible - capable of bending easily without breaking.
-cyte
Pertaining to cells
Lymphocyte - a type of white blood cell that is part of the immune system. There are three main types of lymphocytes: B cells and T cells and natural killer (NK) cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.
-derma
Of the skin
Leukoderma
Also called achromoderma, is a clinical sign describing a localised area of white depigmented skin due to total loss of epidermal melanin. It is not a diagnosis in itself and has many causes. Leukoderma must be distinguished from hypopigmentation, which is pallor due to reduced pigmentation.
-ic
Pertaining to
Hypodermic - relating to the region immediately beneath the skin.
-megaly
Oversized, larger than normal
Cephalomegaly - enlargement of the head; enlarged head; too large of a head.
Acromegaly
A rare condition where the body produces too much growth hormone, causing body tissues and bones to grow more quickly. Over time, this leads to abnormally large hands and feet, and a wide range of other symptoms.
-itis
Inflammation of
Gastritis - inflammation (irritation) of the stomach lining
Periocarditis
Swelling and irritation of the thin, saclike tissue surrounding the heart (pericardium).
-oid
Resembling or like
Lipoid - relating to or resembling fat.
Ovoid
The meaning of OVOID is resembling an egg in shape
-oma
Tumour
Melanoma -
Carcinoma
Cancer that forms in epithelial tissue. Epithelial tissue lines most of your organs, the internal passageways in your body (like your esophagus), and your skin.
-osis Also –a or -y
Abnormal condition of
Cyanosis - medical term for when your skin, lips or nails turn blue due to a lack of oxygen in your blood.
-stasis
State or condition of equilibrium, can also refer to a slowed or stopped flow of fluid.
Homeostasis - any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it’s unsuccessful, it results in a disaster or death of the organism.
Metastasis
The process by which cancer cells spread to other parts of the body is called metastasis
Venous stasis
If you have venous stasis, your veins can’t send the blood from your legs back to your heart. Blood pools in the lower legs and creates swelling, pressure and skin problems.
-static
In the condition or state of, stable
Homeostatic - the regulation of body temperature, and the balance between acidity and alkalinity. It is a process that maintains the stability of the organism’s internal environment in response to fluctuations in external environmental conditions.
-trophy
Pertaining to cells, tissue or organs their state or development
Dystrophy - Dystrophy is defined as the process and consequences of hereditary progressive affections of specific cells in one or more tissues that initially show a normal function. Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass.
Atrophy
The meaning of ATROPHY is decrease in size or wasting away of a body part or tissue
Hypertrophy
An increase and growth of muscle cells
