Study Notes
Magakaryocyte
- Megakaryocytes are not spermatids or thyroid follicular cells.
Ovulatory Development
- Ovulatory development is assessed via the amount of fluid in the antrum to determine readiness for in vitro fertilization.
Muscle Regeneration
- Satellite cells are used to regenerate damaged muscle cells.
Cilia Movement
- Dynein mediates the beating or weeping of cilia.
Mitochondrial ATP Synthesis
- ATP synthesis occurs in the inner mitochondrial membrane where the cristae are located.
Alveoli Respiration
- Pneumocytes type II create surfactant, which decreases friction in the alveoli during respiration.
Blood Vessel Stain
- A stain with anti-actin antibodies marks the tunica media of a blood vessel.
Oxytocin Secretion
