In this chapter's tools
Lab practical image sets 1
- Histology station: exocrine and endocrine glands
Prediction scenarios 3
- Level 1 a regulated variable rises above its set point
- Level 1 extracellular potassium rises, predict resting potential
- Level 2 sodium channels are blocked, predict the action potential
Pathways 3
- Action potential basics: stimulus to repolarization
- Second messenger cascade: hormone to cell response
- Tissue repair after an injury
Feedback loops 1
- Generic loop anatomy: stimulus to response (introduces every slot)
Graphs 3
- A regulated variable oscillating around its set point
- Resting membrane potential and the ion gradients behind it
- A generic action potential (threshold, all-or-none)
Comparison tables 6
- Mucous vs serous vs cutaneous vs synovial membranes
- Negative vs positive feedback
- Graded potential vs action potential
- Nervous vs endocrine signaling
- Water-soluble vs lipid-soluble messengers
- Endocrine vs exocrine glands
