Learning Modules Flashcards
mesothelium?
he epithelium that lines the pleurae, peritoneum, and pericardium.
Peritoneum
serous membrane that forms the lining of the abdominal cavity
Mesothelioma
a cancer of mesothelial tissue
name the 4 body cavities in development and what they give rise to
pericardial cavity (pericardium), pleural cavities, gives rise to the forming pleural space, and the abdominal-pelvic cavity.
why does the diaphgragm form so early
to separate the body cavities and to prevent the abdomenal organs from pushing up so far that the lungs will be too small
what lines a body cavity
mesothelium
what does the mesenchymal cells do
gives rise to blood capillaries that secretes serious fluid to lubricate the surface
does the lung develop symmetrically?
no
COELUM?
body cavity
SIMPLE EPITHELIUM ?
a single layer of cells supported by a basement membrane.
SEROUS FLUID:
fluid derived from blood plasma , rich in fluid and proteins. Lubricates the body cavities allowing frictionless sliding movement.
ASCITES
usually excess fluid containing cells produced by the mesothelium.
PERICARDITIS
inflammation of the pericardium
HEMOTHRORAX
blood in the thoracic cavities (pleural or pericardial cavities)
PNEUMOTHORAX
air in the pleural cavities
Suspensory ligaments?
connective tissue run from the skin towards the dense connective tissue around the muscle
areolar tissue to the dense connective tissue around the pectoralis major.
Retro mammary bursa?
a well-defined loose areolar tissue between the deep layer of superficial fascia on the posterior aspect of the breast
where does the mammary gland DEVELOP from
embryonic surface epithelium into the underlying mesenchyme
where does the mammary gland DEVELOP from
embryonic surface epithelium into the underlying mesenchyme
where are the mammary glands LOCALISED
mammary gland (with sweat glands, hair ) are subsequently localized in the loose connective tissue /superficial formed from the mesenchyme (fascia) in later development)
is which direction does the breast develop into
towards the axillary process (tail) of breast
what surrounds the nipple
areola
muscle of the breast
pectoralis major
lactiferous sinuses are?
(milk reservoirs during lactation
lactiferous sinuses are?
milk reservoirs during lactation
Identify the space between the superficial fascia and aponeurosis-what is it called?
retro mammary bursa
lobules of mammary gland?
can be lactating
lactiferous ducts
connect lobules to lactiferous sinus
