The Brain Brainstem The brain stem plays an important role in basic attention‚ arousal‚ and consciousness. It contains the medulla oblongata‚ cerebellum‚ midbrain and pons. Its functions include things that you need to survive‚ such as breathing‚ digestion‚ heart rate‚ blood pressure‚ and arousal which makes you awake and alert.All information from our body passes through the brain stem on the way to the brain. Medulla Oblangata The medulla oblongata connects the brain and spinal cord.

To name a few it is what allows us to move‚ to breathe‚ to talk‚ to remember‚ to think! Without it functioning properly‚ we would literally in some cases be just like a “vegetable.” Our brain is composed of three major components: 1) cerebrum‚ 2) cerebellum‚ and 3) brain stem. The cerebrum’s major function is to generate our thoughts and controls our movement. Also known as the cerebral cortex‚ if you could open your skull and look at what lies underneath‚ that big wrinkly pinkish grey matter that’s

The Nervous System is the system of cells‚ tissues‚ and organs that regulates the body’s responses to internal and external stimuli. In vertebrates it consists of the brain‚ spinal cord‚ nerves‚ ganglia‚ and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system‚ the cranial nerves‚ and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of nerves

body and responds based on this information. Different parts of the brain control movement‚ speech‚ emotions‚ consciousness and internal body functions‚ such as heart rate‚ breathing and body temperature. The brain has 3 main parts: cerebrum‚ cerebellum and brain stem. Cerebrum The cerebrum is the largest part of the brain. It is divided into 2 parts (halves) called the left and right cerebral hemispheres. The 2 hemispheres are connected by a bridge of nerve fibres called the corpus callosum

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch

Develop an outline of the components of the human nervous system‚ inclusive of the CNS (central nervous system) the somatic system‚ and both divisions of the autonomic nervous system (ANS). Include in your outline the major distinctions among these systems. Human Nervous System – Overview The human nervous system is composed of all nerve tissues in the body. The functions of nerve tissue are to receive stimuli‚ transmit stimuli to nervous centers‚ and to initiate response

Part 2 : Explain how your current uses of music might impact your cognitive function. Draw on the research literature from both the “music and the brain” and “music in schools” lectures to support your ideas. Introduction Currently‚ I am largely involved in composing music for interactive media. To be able to produce professional music‚ I am constantly improving my music competency skills through music training. Recent studies have shown that music training enhances higher level cognition such as
