The central nervous system: The brain and the spinal cord form the central nervous system (CNS). The brain controls the body functions by sending and receiving messages through nerves. It is also aids in thought processing. 2. The peripheral nervous system: The network of nerves that branch out from the spinal cord and brain and spread out throughout the body form the peripheral nervous system (PNS).
“Protected within the skull, the brain is composed of mostly of the cerebrum, cerebellum, and brainstem.” (“Anatomy of the Brain, mayfieldclinic.com”) The cerebrum is the biggest part in the human brain, and is divided into lobes including the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Each lobe has its own tasks. For example, “the frontal lobe is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving, the parietal lobe is associated with movement,
TAQ 1: a) b) The mammalian nervous system is split into two. The central nervous system consists of the brain and the spinal cord, which coordinates and controls the movement and activities of the body and the peripheral nervous system, made up of the somatic and autonomic system, which forms the connections between the organs and the central nervous system. The brain and the spinal cord work together to aid the coordination of the body. The brain can be divided into three main regions: the forebrain, midbrain and hindbrain. The forebrain interprets sensory information, thought processes and memory and it also monitors the composition of the blood and temperature on the body.
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.
INTRODUCTION The brain is a delicate and very complex organ located in the head of vertebrate and invertebrate animals. The brain can be said to be the controller of the actions and coordination of an animal. Therefore, the brain should remain unchanged no matter what we take into the body. Nowhere in the body is there more need for homeostasis than in the brain. The blood is a body fluid that circulates constantly.
Most of the action that happens in the brain that is related to sleep is in the hypothalamus, which is located in the Limbic System next to the temporal lobe. The Limbic System is the part of the brain that works with emotions and motives through a network of neural structures; it consists of the hypothalamus, the pituitary
To somewhat contradiction and agreement, Sacks states "some areas of the visual cortex may be reallocated and used to process sound and touch"(Sacks,330). In contrast to Johnson, it is clear that the pacemaker, our brain, allows the visual cortex to reallocate to heighten other senses, which allows the blind people to adjust their new way of life. However, to some extent, Sacks statement bolsters Johnson's case that self-organizing system is a very complex system, just like the complex structure of our brain, which acts as a pacemaker for us. The complexity of a structure is indeed dependent on how efficiently each component is able to carry out its functions, and structures which are deemed complex have different components which it is dependent upon to perform its functions. The idea of pacemaker itself cannot be disregarded in the making of
Not only does the hippocampus recalls information; but, also gives memories meaning and connect them to other means through the cortical regions of the brain (lumen). The cerebellum controls things like procedural memory, motor learning, and classical conditioning. Things that are day to day movements such as blinking your eye is controlled by your cerebellum; you perform the movement without realizing it, because you are used to it (lumen). The brain is a very complex organ that is being utilized all-day and even while you are asleep and processing important
The system is so important because it regulates the body’s metabolism, growth and sexual development, digestion, heart rate, and many of the other body functions regulated by hormones. The first three glands are all located in the brain. The hypothalamus gland connects the endocrine system to the nervous system and also regulates when
