Module 3 Flashcards
Anatomical Position
subject stands straight facing observer; eyes are forward, feet are flat and directed forwards, arms are at side with palms facing forward
Afferent
towards some reference organ
Efferent
away from some reference organ
Superior
towards head or upper portion of body
Inferior
towards feet or lower portion of body
Anterior
nearer to, or at front of body
Posterior
nearer to, or at back of body
Medial
nearer to midline or sagittal plane
Lateral
farther from midline
Intermediate
between two structures
Ipsilateral
on the same side of body as some structure
Contralateral
on the opposite side of body from some structure
Proximal
nearer to the attachment of a limb to the trunk; nearer to point of origin
Distal
farther from attachment of limb to the trunk; farther from point of origin
Superficial
towards/on the surface
Deep
away from the surface of the body
Plane
imaginary flat surface that passes through region of body
Sagittal plane
vertical plane that divides the body/organ into left and right sides
Frontal (coronal) plane
vertical plane that divides the body/organ into front and back (anterior and posterior)
Transverse Plane
horizontal plane that divides the body into upper and lower portions (superior and inferior)
Parasagittal plane
does not run through midline; divides body into UNEQUAL left and right portions
Midsagittal plane
vertical plane that runs down midline and divides body into EQUAL left and right halves
Oblique Plane
passes through body/organ at an angle between transverse plane and sagittal plane or between transverse plane and frontal plane
Section
cut of the body/organ made along one of the planes
Dorsal body cavity
1/2 body cavities; contains cranial and vertebral cavity
Cranial cavity
part of dorsal cavity; enclosed by cranial bones; contains the brain
Vertebral Cavity
part of dorsal cavity; formed by vertebral column; contains spinal cord
Thoracic Cavity
part of ventral cavity; the chest; contains pleural cavity, pericardial cavity and mediastinum
Pleural cavity
within thoracic cavity; surrounds each lung; serous membrane= pleura
Pericardial cavity
within thoracic cavity; surrounds the heart; serous membrane= pericardium
Mediastinum
within thoracic cavity; central portion btw lungs; contains heart, thymus, esophagus, trachea and several large blood vessels
Abdominopelvic Cavity
part of the ventral cavity; extends from diaphragm to groin; contains abdominal cavity and pelvic cavity
organs within this cavity are called VISCERA
Ventral Cavity
1/2 body cavities; contains thoracic cavity, and abdominopelvic cavity
Abdominal cavity
part of abdominopelvic cavity in ventral body cavity; contains stomach, spleen, liver, gallbladder, and sm/lg intestines
serous membrane= peritoneum
Viscera
organs found in the abdominopelvic cavity
Pelvic cavity
part of abdominopelvic cavity of ventral body cavity; contains bladder, portion of large intestine, and internal organs of reproduction
Serous membrane
covers viscera (organs) within thoracic and abdominopelvic cavities; composed of two layers (parietal and visceral)
Parietal layer
layer of serous membrane; lines walls of cavity
Visceral layer
layer of serous membrane; covers and adheres to viscera (organs) within cavity
Serous fluid
found btw visceral and parietal layers of serous membrane; function to reduce friction and allow organs to move and lungs to inflate/deflate
Right Hypochondriac Region
1/9 abdominopelvic regions; right outer portion; contains portion of right lobe of liver
Epigastric Region
1/9 abdominopelvic regions; central region, containing sternum and large portion of stomach and gallbladder, transverse colon of lg intestine, and left lobe of liver
Left Hypochondriac Region
1/9 abdominopelvic regions; left outer portion; containing spleen and ribs
Right Lumbar Region
1/9 abdominopelvic regions; outer portion below right hypochondriac; contains ascending colon of lg intestine,
Umbilical Region
1/9 abdominopelvic regions; central region (where naval is); contains small intestines,
Left Lumbar Region
1/9 abdominopelvic regions; outer portion below left hypochondriac; contains descending colon of large intestine
Right Iliac (Inguinal) Region
1/9 abdominopelvic regions; below right lumbar; contains cecum and appendix
Hypogastric Region
1/9 abdominopelvic regions; pubic region below naval; contains urinary bladder
Left Iliac (Inguinal) Region
1/9 abdominopelvic regions; below left lumbar; contains initial part of sigmoid colon (large intestine)
