Some of these incoming fibers go to the motor nucleus of the trigeminal nerve (V), bypassing the pathways for conscious perception. The jaw jerk reflex is an example; tapping the jaw elicits a reflex closure of the jaw in the same way that tapping the knee elicits a reflex kick of the lower leg.
FSH stimulates the production of eggs and LH stimulates the release of the egg. FSH and LH are produced by the pituitary gland in the brain. There are four stages in the menstrual cycle. Stage 1. Days 1-4. Menstruation (bleeding) occurs. The lining of the uterus disintegrates and is shed. This is due to low levels of progesterone. Stage 2. Days 4-14. The uterine lining grows back.
The trophectoderm and uterine endometrium both express adhesion molecules. During the implantation window, the absorption and movement of uterine fluid presses the blastocyst up against the uterine wall. The blastocyst will attach to the uterine wall at the area immediately above the inner cell mass. Cells of the trophectoderm will then begin invading the endometrium. -the movement of fluid towards the proximity and allow for communication and attachments.
