- What are the five senses?
- In your own words, describe the three sections of the ear AND how each section works to allow a person to hear. (3 marks)
- What does the autonomic nervous system control? (2.5 marks)
- What are schemata? (2 marks)
- What part of the brain affects sleep, dreaming and respiration? (1 mark)
- Describe the difference between the midbrain and the hindbrain. (4 marks)
- In your own words, describe the difference between sensation and perception, and give one example that explains your understanding. (4 marks)
- The five senses are sight, smell, hearing, taste, and touch.
- The ear is made up of the outer ear, middle ear and inner ear. The outer ear works by helping you to locate the original place of a sound (collects the sound of outside forces). The middle ears job is to take those sound waves (which are transmitted throughout the outer ear) and produce them into vibrations for the inner ear. The inner ear responds by using the tiny hairs found in it. The vibrations from the middle ear make the hairs move, and create nerve signals. Our brain understands those signals as sound and put everything together so we can understand what the sound is saying.
- The autonomic nervous system controls andregulates the functions of our internal organs. Examples include the heart, stomach and intestines.
- We develop schemata in our brains, which represent the knowledge we know about ourselves, others and our roles in the social world.
- The pons in our brains affects sleep, dreaming and respiration.
- The hindbrain is responsible for receiving signals from other parts of the brain and from the spinal cord. The midbrain is responsible for holding many major structures in the brain. It interprets signals and relays the information to a more complex part of the brain or causes the body to act on it.
- Sensation deals with physically feeling a sense. It is “the process in which a sensory receptor is stimulated”. This produces nerve impulses that travel to the brain and your body interprets it as a certain sense. Perception is the process of translation and interpretation in the brain. It helps us understand the information we receive from our physical stimuli.
