今天由于网络原因,只进行了一篇听写,同时要承认,这篇只是完成了纠错和查词的工作,并没有完全跟读,看来还要加油。
Anatomy: The Brain
Listen to part of a lecture in ananatomy class.
I've brought in a picture of the human brain today, which we are going to look at and discuss in detail. The partsof the brain that we are going to talk about today are clearly labelled. The brain is like our command center for all our daily functions and allows us to cope with our environment. How we communicate with words, actions, thoughts, andfeelings are all centered in the brain. Some researchers believe that the brain is so complex and mysterious that we will never be able to fully understand it. Somehave even referred to it as a little"black box" like those found on a plane that contain all the critical and highly confidential information of the flight. That being said,there are parts of the brain that we do know about, like the parts listed on the diagram, and we also know their functions that each bring to make our body work. It's easiest to think of the brain as three connected parts: the cerebrum, brainstem, and cerebellum.
Let's start off with the brainstem, which is found at the bottomof the brain and joins the cerebrum to the spinal cord. The brainstem has an important role because it controls lots of critical functions including respiration, regulation of the heart rhythms, basic aspects of sound localization, which allows usto identify the origin of adetected sound, andreflexes. Asyou can see on the diagram, the brainstem includes the midbrain,the pons, and the medulla. These allow functions such a sthe movement of eyes and mouth, passing on sensory messages like hot, pain, loud, and other functions such as hunger,consciousness, body temperature, sneezing,coughing, vomiting and swallowing.
Next, we'll look at the second largest part of the brain: the cerebellum. It is located atthe lower back of the head and is attached to the brainstem. It is made upwith two hemispheres and its functions are to control complex voluntary motor functions such as walking, balance and posture.
The third and largest part of our brain is the cerebrum. Its associations are conscious thought, movement and sensations such as touch, vision, hearing, judgment, reasoning, problem solving and emotions. It is made up withtwo halves, with each half controling the opposite sideof the body. The corpuscallosum connects the two halves, and delivers messages between them. There are four lobes that make up the cerebrum, the frontal, temporal, parietal, and occipital. The frontal lobeis located in the front of thehead and is involved in personality, charateristics and movement. The parietal lobe is the middle part of the brain, and helps you to identify objects and understand spatialrelationships like where your body is compared to objects around you. It also helps make meaning of pain and touch in thebody. The occipital lobe allows you to see and is located at the back of thebrain. Finally, the temporal lobe assists with memory, speech, and sense of smell and is found at the sides of thebrain.
The average weight of the adult humanbrain is anywhere between 1 and1.5 kilograms. Some people saythat we only use 10% of our brain, but this is just a myth. In fact,we use our entire brain. That being said, we canclaim that most people only use a very small fraction of the cognitive potential of their brains. Different cultures have used several methods to improve their cognitive potential such as reading, education, puzzle solving and critical thinking. I hope this brief introduction to the brain helps you understand the brainand its different functions.
