Document Summary
Spermatogenesis: spinal cord, dorsal : sensory - afferent, ventral: motor- efferent (sending signals out, figure 12. 6 *, how is csf made and describe how it travels through ventricle system & 16. 7: 2 lateral ventricles, intraventricular foramen, ependymal cells in the choroid plexus, each ventricle has a choroid plexus, start in the lateral ventricles at that choroid plexus. Tongue pressing the food against hard palate. Elevation of soft palate (palatal muscles: pharyngeal phase. Elevation of the larynx, folding of the epiglottis. Constriction of pharyngeal muscles push bolus into the esophagus: esophageal phase. Bolus is pushed down the esophagus in peristalsis waves. Opening of the lower esophageal sphincter: enters the stomach. Mechanical breakdown (3 layers of muscle and how it can mix) Chemical breakdown (histology of the stomach wall: mucous cells=mucin= lubrication, parietal cells = hcl and intrinsic factor=vitamin b12, chief cells = Pepsinogen = pepsin by hcl, g cells= gastrin)
