Lab 1: Anatomy Academy Flashcards
Atoms
smallest units of matter
Molecules
one or more atoms joined together
Organelles
parts of cells, made of molecules
Cells
basic unit of life, composed of organelles working together
Tissues
groups of cells massed together to perform specific function
Organs
parts of the human body, made up of tissues
Organ Systems
body groups of organs that work together to provide a similar/coordinated body function
Organism
contiguous living system
Anatomical Position
toes forward, arms straight at sides, palms forward, fingers downward, face directly forward
Superior
above
Inferior
below
Anterior
in front
Posterior
in back
Lateral
moving away from midline of body
Medial
moving toward body midline
Dorsal
on the back
Ventral
on the belly
Cranial
on the head
Caudal
toward the tail (region)
Superficial
on the surface
Deep
below the surface
Intermediate
between (need 3 reference points)
Sagittal Plane
dividing left and right
Midsagittal
plane dividing left and right exactly down the middle
Parasagittal
plane dividing left and right down any other location except the midline
Frontal Plane
(Coronal Plane) plane dividing front and back
Coronal Plane
(Frontal Plane) plane dividing front (anterior) and back (posterior)
Transverse Plane
plane dividing top (superior) and bottom (inferior)
Oblique Plane
plane intersecting at any angle ≠ 90 degrees
Dorsal Cavity
body cavity that holds the brain and spinal cord
Ventral Cavity
body cavity that houses familiar body organs
Cranial Cavity
part 1 of 2 in dorsal cavity; holds brain
Spinal (Vertebral) Cavity
part 2 of 2 in dorsal cavity; holds spinal cord; made from hollow holes (foramen) in vertebral column
Thoracic Cavity
part 1 of 2 in ventral cavity; holds lungs, heart, esophagus and trachea; floors at the diaphragm
Abdominopelvic Cavity
part 2 of 2 in ventral cavity; holds liver, spleen, intestines, stomach, gall bladder, pancreas, bladder, reproductive organs; superior wall = diaphragm
Abdominal Cavity
1 of 2 of abdominopelvic cavity; contains digestive organs
Pelvic Cavity
2 of 2 of abdominopelvic cavity; contains lower region of digestive organs, reproductive organs and the bladder
Mediastinum
cavity within thoracic cavity, contains the heart, pericardium, trachea, esophagus some of bronchi and thymus
Cutaneous Membrane
the skin
Mucous Membrane
inner lining of most hollow organs
Synovial Membrane
in joints to assist with lubrication
Serous Membrane
membranes that separate organs from rest of body and provide barriers between organs and body walls to reduce friction during movement
Membrane
thin, pliable tissue that helps to define the body and enclose or separate one region from another; involved in some kind of secretion and regenerate quickly
Serous Membrane Locations
on interior body cavity walls or directly on the surface of organs; on lungs, heart and many other abdominal organs
Parietal Serous Membrane
part of serous membrane found on the walls of cavities
Visceral Serous Membrane
part serous membrane found on the organs directly
Pleura
pertaining to the lungs or rib cage
Pericardium
pertaining to the heart or the lining around the heart sac; name for the sac itself and the membrane surrounding the heart within it
Peritoneum
pertaining to the abdominal organs or walls
Visceral Pleura
serous membrane located on the lungs
Parietal Pleura
serous membrane on the body wall of the rib cage
Visceral Pericardium
serous membrane on the heart
Parietal Pericardium
serous membrane on the interior of the fibrous pericardium
Fibrous Pericardium
fibrous sac that surrounds the heart to provide extra support
Parietal Peritoneum
serous membrane on the abdominal body wall
Visceral Peritoneum
serous membrane on the walls of abdominal organs (live, stomach, intestines, gall bladder)
Mesentery
double-layered visceral peritoneum (as seen on and around intestines)
Lesser Omentum
small apron of visceral peritoneum above the stomach and riddled with fat for excess organ insulation
Greater Omentum
large apron of visceral peritoneum below the stomach and riddled with fat for excess organ insulation
Serous Fluid
fluid produced within and created by the serous membrane to lubricate body cavities; made from interstitial fluid (as between cells)
Pericardial Cavity
cavity between the visceral and parietal pericardium
Pleural Cavity
cavity between the visceral and parietal pleura
Peritoneal Cavity
cavity between the visceral and parietal peritoneum
