White matter is a component of the central nervous system, in the brain and superficial spinal cord, and consists mostly of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another and between the cerebrum and lower brain centers. Gray matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and myelinated as well as unmyelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries. Grey matter is
Each of these lobes has different functions from each other. On the other hand, the neurotransmitters are the information carriers, they carry electrochemical signals to and from the brain throughout the entire body in human beings. Then, we have the nervous system which can actually be divided into two parts, the central nervous system (CNS) and the peripheral nervous system (PNS) where the brain and spinal cord are parts of the CNS. The PNS can still be divided into two specific parts, the somatic nervous system (SNS) and the autonomic nervous system (ANS). While the SNS directs the movements of the skeletal muscles, the ANS regulates involuntary processes such as the heart beating, breathing, blood pressure, and blood sugar level.
The brain is a powerful organ if you understand its full potential. The brain has two main communication systems, the nervous system and the endocrine system. According to Zimbardo, Johnson, & McCann (2012) “Out of the two, the fast acting nervous system carries messages in pulses of electrical and chemical energy through the body; the slower endocrine system sends follow up messages that support and sustain the response initiated by the nervous system”. Neurons are the building block of the nervous system. Sensory, Motor, and Interneuron are the three major classes of neurons.
A conclusion will then be drawn based on the discussion. The brain is an essential organ of the body. It is the control center for all the body’s activities, such as walking, talking, swallowing, breathing taste, smell and heart beat. The brain also controls our thinking functions, our intellectual activities as well as our emotions. Hemispheric specialization refers to the dominance of one hemisphere of the brain in specific functions, such as language, emotions, motor control and so on ( Feldman, 2009).
(2000) defines the frontal lobe as the part of the brain that controls important cognitive skills in humans. It is located in the front of the brain deep to the frontal bone of the skull. It plays an integral role for example the following functions that is memory formation, emotions, decision making/reasoning, personality, conscious thought, behaviour, planning, organizing, problem solving. The frontal lobe is the most uniquely human of all the brain structures. It is also responsible for primary motor function, or our ability to consciously move our muscles, and the two key areas related to speech, including Broca’s area.
Nervous tissues are found is all organs in the body some have more than others thought, Maximum in the nervous system, least in fatty deposits. Some examples are brain which is a main nervous tissue but also an organ also the heart that is one of our most important organ but also a nervous tissue. Here’s a labelled picture of a nervous tissue; http://biologyonline.us/Online%20A&P/AP%202/Northland/AP2lab/Lab%201%20online/lab1/images/Picture14.jpg Epithetical tissue The function of the epithetical tissue include transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretions of waste products. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers.
There is part of the brain that is the reticular formation, which is also referred as the reticular activity system. It is referred to the reticular activity system because it plays a major role in the arousal stage. “Arousal is not the only function that the reticular formation is involved in; sleep attention, mobility, and the maintenance of muscle, as well as other cardiac, circulatory, respiratory reflexes”. Metencephalon The metencephalon is much like the myelencephalo. This is the part of the brain where the ascending and descending tracts are housed.
The Brain and Behavior Sandra Bradley BEH/225 12/14/2014 Latoshia Stamps The frontal lobes and temporal lobes have different roles regarding behavior. The frontal lobes are located in the front of the brain and are involved with “higher mental abilities and play a role in your sense of self” (Coon, D. & Mitterer, J. O., 2013). They are involved with higher mental abilities such as planning and reasoning, problem solving and judgment, impulse control and language, and social and sexual behavior. There is also an area located at the rear of the frontal lobes called the primary motor cortex. This area of the brain control motor function and directs the body’s muscles.
These hemispheres have been responsible for the development of human language, abstract thought, imagination, and consciousness. The neocortex is flexible and has almost infinite learning abilities. The neocortex is also what has enabled human cultures to develop. These three parts of the brain do not operate independently of one another. They have established
Cognitive psychologists believe that mental processes and stored representations of the world determine behaviour and are central to human experience. Psychologists see the mind as a complex machine – where they believe that it is useful to model mental processes using an information-processing approach whereby: Information is examined from the outside world is received and encoded, Storage and representation of this information to ourselves, Ways in which this information is manipulated and used by the individual, And how we output information back into the world to be received by others.
