1: Systems Flashcards
3 types of gross anatomy
Surface- landmarks
Regional- everything in that region
Systemic- everything in that system
2 types of microscopic anatomy
Cytology- individual cell
Histology- tissues (cell groups)
How do we build from an atom to a person
Atom Molecule Cell Tissue Organ System Person
What’s in the endocrine system
Pineal Pituitary Thyroid Parathyroid Thymus Adrenal Pancreas Ovaries/ testis
What’s in the lymphatic system
Thymus
Spleen
Lymph nodes
Lymphatic vessels
What’s a disease
Homeostasis is overwhelmed due to organ system malfunction
How do we achieve homeostasis
- Receptors sense change
- Control center decides how to fix it
- Effector decodes and acts based on control center
Negative feedback
Senses problem and creates balance
Positive feedback
Senses solution and reinforces
