‘Human behavior and performance are the result of multiple influences.’ Examine and assess this assertion, drawing on examples from Chapters 1, 6 and 7 of Discovering Psychology. How a human behaves and performs is influenced by a variety of internal and external influences. This essay will outline and assess influences that are related to the formation of language, personality and friendship. This will be achieved by evaluating the strengths and weaknesses of evidence collated from studies and experiments. This essay will aim to conclude that the theory of influences does affect human behavior and performance.
Neural Regulation of Mechanical Digestion 4. Identify three neural systems that control the mechanical movements in the GI tract. a. CNS b. ANS-Long Reflexes c. ENS-Local Reflexes 5. Describe the role of the CNS with regard to swallowing. What is the stimulus?
Unit 7 Assignment 2: The Effects of Selected Drugs and Diseases on the Central Nervous System 1. The CNS otherwise known as the Central Nervous System is comprised of the brain which is continuous with the spinal cord. Since the CNS is made up of the brain and spinal cord it is protected by the hard bony skull and vertebral column. (Pages 418- 420) 2. The BBB also known as the Blood Brain Barrier which in conjunction with the Cerebrospinal Fluid or CSF is what nourishes and protects the cells of the CNS.
The human brain can be considered the most complex organ in the human body and also the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists can identify areas within it that perform specific functions. Your brain is organized into three interconnected layers: the central core, limbic system and the cerebral cortex, all of which contain structures that regulate everyday life. (The Human Brain, Discovering Psychology) The central core is found in all vertebrates. Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance and sleep and the early stage of processing sensory information.
Often the midbrains, pons and medulla are referred together as brainstem. The telencephalon comprises of three elements which are the cortex, limbic system and the basal ganglia whilst the Diencephalon consists of the thalamus and hypothalamus. THE FOREBRAIN THE CEREBRAL CORTEX The cerebral cortex is a thin mantle of gray matter covering the surface of each cerebral hemisphere. The most notable features of the telencephalon are the two large and roughly symmetrical hemispheres’ which are in fact separate functional systems interconnected by major fibre pathways called the cerebral commissures. The principal commissures is the corpus callosum which according to Nearve (2008) literally means “hard body” and this wrist –thick bundle of fibres connects the corresponding regions of
Normal aggressive behaviour involves an interaction of a system of structures, as opposed to being dependent on separate brain structures. One part of this system is the Amygdala. This is a structure inside the temporal lobe which, plays an important role in the mediation of affective activities and on the expression of mood; mainly fear, rage and aggression. The amygdala is connected to many structures in the brain including the hippocampus, thalamus and pre frontal cortex. It is fundamental for self-preservation as it enables the identification of danger; therefore exhibiting clear links to aggression.
I will explain the basic ideas of functionalism and explain how common-sense plays a role in the theory. I will then present one objection to the common-sense functionalism theory and form a hypothesis of how a common-sense functionalist would respond to the objection. Lastly, I will present my own evaluation of the common-sense functonalism theory. Functionalism, in simple terms, is the doctrine that the function of an object should determine its design and materials. It is a doctrine in the philosophy of mind according to which mental states are defined by their causes and effects.
This system contains two major types of neurons: sensory neurons (or afferent neurons) that carry information from the nerves to the central nervous system, and motor neurons (or efferent neurons) that carry information from the brain and spinal cord to muscle fibers throughout the body. The Autonomic Nervous System The autonomic system is the part of the peripheral nervous system responsible for regulating involuntary body functions, such as blood flow, heartbeat, digestion and breathing. This system is further divided into two branches: the sympathetic system regulates the flight-or-fight responses, while the parasympathetic system helps maintain normal body functions and conserves physical
