      @Jackline: The human body has a well developed nervous system that is sensitive to various stimuli/or environment. Various body parts have nerve endings that relay information to the Central nervous system (CNS) through string like structures called neurons (Receptor neurons). In return the response is communicated from the CNS to the site by effector neurons. Pain is actually the response from the brain or rather CNS in response to the stimuli which is the canning.

      The same applies to taste i.e if the stimuli is sugar on the tongue,,, the response is sweet taste

      2. Menstruation is the pride of every woman. Females are created to produce eggs (ova) that should be fertilized by sperms to make a baby. Every month one egg matures. If this egg is not fertilized, It will degrade and flow in form of menstruation. Thats why pregnant mums dont menstruate because their carry a fertilized egg and during pregnancy they cease to produce more eggs till delivery.

      Question 1: The body has an elaborate system called the central nervous system (CNS). The CNS has sensory nerves which detect any changes in the environment/stimuli including pain from any part of the body. Once the stimuli received, in this case pain, the information is relayed to the brain via the nerves for interpretation evoking an appropriate response, e.g. crying or shouting or even trying to run away.

      Question 2: The menstrual cycle results from a series of changes in a female body in preparation for the possibility of pregnancy. These monthly changes are caused by hormonal changes. Each month, one of the ovaries releases an egg — a process called ovulation. At the same time, hormonal changes prepare the uterus for pregnancy. If ovulation takes place and the egg isn’t fertilized, the lining of the uterus sheds out. This is a menstrual period.

      1. You have something called pain receptors (nociceptors) in your skin that is connected to a nerve in your body. The nerve is then connected to the other nerves then to the spinal cord which is further connected to the brain in a specific part responsible for physical sensation. So when caned the receptor will do the relaying of information to that part hence the pain. People have been trying to play around with this system to see if pain feeling could be stooped. Would it be nice?

      2. Every month, the female body releases some hormones that cause the lining of the uterus (or womb) to thicken. The thickening is in readiness of the fertilized egg (from the female) by the sperm from a male. if this monthly egg is not fertilized, the thick lining in the uterus breaks down. the materials from the breakdown have to be passed out which is the blood seen or in other words menstruation. If the egg that matures every month is fertilized then the uterus lining will accommodate it and develop to a fetus and no breakdown of the wall would occur thus no menstruation

      Hey Jackline!
      1. Our bodies respond to just about everything in our environment! In particular, our bodies have developed ways to let us know that we are doing something that might “hurt” us. So, when one is caned, the force from the cane might damage to the skin/tissue around it, so your body has prepared a response where the nociceptors in the skin will communicate the mechanical pressure from the cane to a signal in your brain that tells you “alert! don’t repeat this again, alert!”. And that signal is what we know to be “pain” after a caning.
      2. The menstrual cycle is the process that female bodies go through in order to prepare the woman to support a baby as it grows in the uterus. This process is organized by a host of tightly regulated hormones that tell the body what to do at each step. For example, at one point of the cycle, the ovaries make hormones called estrogen and progesterone which cause the womb/uterus to have a thick lining. This lining is to provide nutrients and housing for the fertilized egg (if there is one in that cycle). If not, the lining will break down and then out it goes. It takes about 1 month or so for the whole cycle to complete, hence why there is bleeding every month or so.
