Homeostasis
Maintains normalcy in the human body
Anatomy
- structure and organization
What is anatomy?
-development process
- micro organization
- structure of the body
Division of anatomy
- Gross anatomy
-micro anatomy - radiographic anatomy
- pathologic anatomy
Gross anatomy subdivision
-Systemic anatomy
- regional anatomy
- surface anatomy
-embryology
- comparative anatomy
Systemic anatomy
- Studies the anatomy of each functionalsystem
Regional anatomy
- study anatomy region by region
-ex head outermost skin & head (integramenty system) → skull (skeletal system )→ present micninjas made of connective-tissue system → protect the brain → brain ( nervous system) →carrying away nutrients from brain (cardiovascular systems)→gasious exchange ( respiratory system)
-studying multiple systems together as they relate to a region
present meninges
- made up of connective tissue→protective layers that are protecting the brain
Nervous system
-Blood vessels that are running through the structures of the brain → bring food to the brain cells → carrying a way the waste
How is 02 brought to the brain?
Via the blood
How does 02 get into the blood?
Through the lungs by gasious exchange
Surface anatomy
- Focuses superficial anatomic markings and internal body structures as they relate to the skin covering them
-ex annual physical physician feels lymph nodes to ensure they are not enlarged→physician studying organs through surface anatomy
Embryology
Studies developmental changes from fertilization to birth
Comparative anatomy
Examines similarities and differences in the anatomy of different species
Ex cat-and human have same muscles
Microscopic anatomy division
-cytology
- histology
Cytology
-Study of individual cells and their internal structure
Histology
Study of tissues
Pathologic anatomy
Examines aratomic changes caused by disease considers both gross and micro anatomy
Similar to comparative anatomy same species health vs non healthy
Radiographic anatomy
Investigates the internal structures of the body not invasive!
Ex xray / anatomical imaging l synogruphy/CT/DSA/MRI/ pet scan
What is xray good for
Bones teeth and dense structures like tumors
What are the disadvantages of xray
High energy radiation
Does not image sett tissue well
Sonography
- Sater than X-ray
- as the wand is moved across the body high frequency ultrasound that produce an image = sonogram,
Computed temography Ct cat scan
- low intensity xrays are emitted from one side of the machine pass through the body and collected by detectors on the opposite side
- continuous thins slices of images = formed
- the slices can be put together and reconstruct a 3d image of the body
Why is the CT better than the xray
Because it takes many images in thin slices
