Psy 240 the Brain
The brain is an amazing arrangement. It is the most rigid and interesting part of the human body. It is like a computer that controls every part of the body. The brain consist of many millions of neurons cells that support the brain system this is called Glial cells (Pinel 2011 p.55)
The neurons in the brain process information and these are the nervous system communication device. Neurons can be broken down into four structures. These are soma, the cell body which shields and protect the nucleus. Dendrite is the branch like mechanism that the neurons obtain information. Axon the long thin tube structure that take the information sent from the soma to the terminal buttons and the terminal buttons are small knob structure at the end of each branch of the axon. These buttons discharge neurotransmitters.
The forebrain is made up of the telencephalon and the diencephalon. The midbrain comprises of mesencephalon which is can be broken down into the tectum and the tegmentum. The hindbrain consists of the metencephalon which is broken down into the cerebellum, Pons, and myelencephalon which is made up of medulla oblongata.
The Telencephalon is at the largest part of the brain and is made up of the basil ganglia, the cerebral cortex, the olfactory bulb, and the corpus striatum. The functions of the telencephalon are: Initiating voluntary movement, determines intelligence, determines personality, interprets sensory impulses, facilitate complex cognitive processes such as learning, speaking and problem solving, sense of smell and sense of touch (Pinel 2011 Ch.3 p.66).
The Diencephalon sits between the cerebral hemispheres and is superior to the midbrain, which is made up of the thalamus and hypothalamus structures. The functions of the diencephalon include: Sensing impulses directed throughout the Body, Controlling autonomic functions, controlling endocrine functions, controlling motor functions, homeostasis, Hearing, Vision, Smell, and Taste and Touch

    The human brain is one of the most complex and fascinating parts of the body. The major regions of the brain are separated into three layers called the central core, the limbic system, and the cerebral hemispheres or otherwise called the forebrain, midbrain, and hindbrain. The forebrain houses the cerebrum, thalamus, and hypothalamus. The midbrain houses tectum and tegmentum. The hindbrain houses the cerebellum, pons, and medulla. From here the brain is divided into five major divisions. They are called the telencephalon (forebrain), the diencephalon (forebrain), the mesencephalon (midbrain), the metencephalon (hindbrain), and the myelencephalon (hindbrain).…

    The command center of the human nervous system is the brain. The sensory organs send information to the brain, which then sends output to the muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem, and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex, which has four lobes. There is a frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The brain develops from three sections known as the forebrain, midbrain, and hindbrain. There are two hemispheres, the left and the right. These two hemispheres are connected by a bundle of nerve fibers called the corpus callosum.…

    The mentencephalon is located under the rear area of the cerebrum and above the medulla oblongata. This structure is made up of the cerebellum and pons (the connection to the cerebellum). The functions of the metencephalon include arousal, balance, cardiac reflexes, muscle movement and maintenance, and sleep. Along with the myelencephalon, they represent the hindbrain.…

    The largest portion of the human brain is the cerebrum. Also known as the cortex, the cerebrum is involved with higher brain functions like thought and action. The cerebral cortex has four lobes – the frontal lobe, the parietal lobe, temporal lobe, and the occipital lobe (“Brain Structures and their Functions,” n.d.; “Frontal Lobe - The Brain Made Simple,” n.d.).…

    The cerebral cortex is “a large, deeply wrinkled sheet of neurons, or nerve cells, on the surface of the brain’s two hemispheres”. These are defined as the right and left hemispheres and make up the largest volume in the brain. The cerebral cortex controls all sensation, thought, comprehension, higher cognition, ideas, language, memory and emotion (Pinel, 2011). The hemispheres consist of four lobes, with each performing a specific function (Pinel, 2011).…

    The cerebral cortex is the outer most layer of the brain, and consists of a collection of nerve cells bodies made up from gray matter. The brain is divided into two hemispheres, and in order for communication to take place between each hemisphere the neurons talk to each other, and that’s called corpus callosum. A cool fact about a human cerebral cortex is that it’s larger than any animal. The cerebral cortex is divided into four lobes that also have the specific and different functions to each lobe, but they also have to all work together. The four lobes are called frontal, parietal, temporal and occipital.…
