List the 3 main cavities of the trunk
1- Thoracic
2- Abdominal
3- Pelvic
What structure separates the thoracic from the abdominal cavity?
Diaphragm
The left and right sides of the thoracic cavity are separated by an area in the middle - what is this called?
Mediastinum
What does the mediastinum contain?
Heart Thymus Esophagus Trachea Blood vessels + nerves
What structures enclose the abdominal cavity?
Enclosed anteriorly by the abdominal muscles: stomach, intestines, liver, pancreas, spleen and kidneys
What structures enclose the pelvic cavity?
Enclosed by pelvic bones
Contains: urinary bladder, parts of large intestine, internal reproductive organs
What quadrant does the appendix lie?
Right lower quadrant
Which quadrant is the spleen located?:
Left upper quadrant
Which quadrant is the urinary bladder located?
Left and lower quadrants
Which region is the liver found
Right hypochondriac and epigastric
Which region is the urinary bladder found?
Hypogastric region
Which region is the large intestine found?
Left iliac region
What conditions would cause organs to move within the abdominalpelvic cavity?
Pregnancy
Central abdominal obesity
Abdominal tumor growth
A man is stabbed with a knife in the epigastric region which organs may be damaged?
Liver, stomach, pancreas, major blood vessels
Describe the parts formed by frontal/coronal plane
Vertical plane
Separates body into anterior and posterior portions
Describe the parts formed by horizontal plane
Separates body into superior and inferior
Runs parallel to the ground
Describe the parts formed by Sagittal plane + mid-sagittal
Vertical plane
Separates body into left and right segments
mid-sagittal divides equally
sagittal divides unequally
Define anatomy
scientific discipline investigating structure of body parts and how they relate to each other
Define physiology
study of the function of living things
What are the different levels of anatomy?
1- Gross anatomy: structures studied without a microscope
a) systemic: system by system
b) regional: region by region
2- Surface: study of external form of the body and its relation to deeper structures
3- Microscopic: structures examined with a microscope
4- Developmental: structural changes throughout lifespan
What are the levels of physiology
1- molecular
2- cellular
3- systemic
4- neurophysiology
Describe the 6 levels of organisation in the body
1- Chemical: atoms -> molecules
2- Cellular: molecules -> organelles
3- Tissue: numerous cells -> tissue
4- Organ: tissues -> organ
5- Organ system: multiple organs with similar function -> organ system
6- Organisms: multiple organ systems -> organism
List the 6 characteristics of organisms
1- organisation 2- metabolism 3- responsiveness 4- growth 5- development 6- reproduction
Define homeostasis
Maintenance of relatively constant internal environment despite the fluctuations in the external environment
List characteristics of anatomical position
Erect person:
- face directed forward
- arms hanging by the sides
- palms facing forward
supine: person lying up
prone: person lying face down
List the directional terms to identify body parts
1- superior: towards the head
2- inferior: towards the tail
3- anterior: toward the front
4- posterior: toward the back
5- proximal: nearest from point of attachment
6- distal: distant from point of attachment
7- medial: toward mid-line of the body
8- lateral: away from the mid-line of the body
9- superficial: close to surface of..
10- deep: towards interior of..
Describe the parts formed by the transverse plane
divides body into superior and inferior
What are the regions used to identify the location of organs? (right to left)
1- right hypochondriac 2- epigastric 3- left hypochondriac 4- right lumbar 5- umbilical 6- left lumbar 7- right iliac 8- hypogastric 8- left iliac
Describe the properties of serous membranes
- serosa
- lines cavities and covers organs
- serous fluid produced by the membrane fills the cavity between the two layers
- serous fluid acts as a lubricant between organ and body wall
Describe the location and function of serous membranes
1- heart: pericardium 2- lungs and thoracic cavity: pleura 3- abdominopelvic cavity: peritoneum 2 layers: a) parietal - lines cavity b) visceral - lines organs
