BSC2085 - Quiz 2

Anatomy - Maser

Negative Feedback change in opposite direction
Negative Feedback by Nervous System reverse stimulus --> return to set point
Negative Feedback by Endocrine System Blood Glucose
Blood Glucose Set Point 90 mg glucose/100 ml blood
Glucose too high insulin (from pancreas) stores glucose as glycogen
Glycogen glucose stored in pancreas
Glucose too low Glucagon (from pancreas) releases glucose from storage
Glucagon releases glucose from pancreas
Positive Feedback change in same direction = increase stimulus
Positive Feedback in Cardiovascular System Blood Clotting - chemicals attract more platelets and clot forms
Positive Feedback in Reproductive System labor contractions - baby's pressure in birth canal --> release of hormone oxytocin --> more contractions
Oxytocin hormone release to increase contractions
Homeostatic Imbalance disease (pathology)
Pathology deviation from a healthy or normal condition
Anatomical Position body erect; arms at sides; palms forward; feet together
Superior toward head/upper part
Inferior away from head/lower part
Anterior toward front
Posterior toward back
Medial toward midline
Lateral away from midline
Intermediate between medial and lateral
Proximal closer to body's axis
Distal farther from body's axis
Superficial toward surface
Deep away from surface/more internal
Axial head/neck/trunk
Appendicular limbs/appendages
Sagittal vertical cut; divides left and right
