Answer:
3. The brain is protected from injury by the skull, meninges, cerebrospinal fluid and the blood-brain barrier. In this post we will explore them all in detail, well, except for the skull since that was already discussed in other posts about the bones. The function of the meninges is to cover and protect the brain itself.
4. If we clean our ears with a pointed object,there is a high risk of damage to Ear Drum.
5. Reflex action is a sudden and involuntary response to stimuli. It helps organisms to quickly adapt to an adverse circumstance that could have the potential to cause bodily harm or even death. Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.
Part E-
1. Brain, spinal cord, nerves
2. Cerebrum- The cerebrum’s function is to direct thought and action through conscious or unconscious motor functions. Before diving too deeply into the functions of the cerebrum, let’s take a quick look at the other parts of the brain. The brainstem is the base of the brain and it is connected to the cerebral spinal column.
Cerebellum- Movement of the body.
Medulla Oblongata- The medulla contains the cardiac, respiratory, vomiting and vasomotor centers, and therefore deals with the autonomic functions of breathing, heart rate and blood pressure as well as the sleep wake cycle.
3. Nerves are a part of the nervous system. They are primarily involved in control and the coordination of all the parts of the body. The nervous system not only sends and receives messages but also processes them into chemical signals called impulses in the human body.
4. As stated before, the chemicals (aroma) present in the food travels from the mouth and into the nasal cavity, where, hair cells carry this information to the brain. However, when we have a cold, the body produces excess mucus, and this mucus prevents the hair cells from sending the information to the brain, as a result, the food that we eat feels tasteless.
5. A healthy diet is essential for both your hair and skin. Wash. Keeping hair and skin clean is crucial, otherwise you'll suffer from a lot of issues. Moisturize. Your hair and skin need moisture to keep them balanced and healthy. Treat. Once a week, give your skin and hair a treat, depending on what they need. Maintain.
