reflexes and how the nervous system arcs and nerve impulses work in order to test out a certain reflex. Hypothesis: The reflex testings’ will show no abnormalities in our nervous system. If we reacted to all the trials then we will not have any abnormalities in our reflexive nervous system. Materials: Lab Partner A rubber hammer (Triangular) A Yard Stick A chart to record your reflexes 1) 2) When the hammer hits the patella the sensory fiber leads into the central nercous system and connects to

looking at both sides of the debate of whether neuroscience replaced psychology in explaining behavior. To begin with we must firstly understand what exactly neuroscience is and what it entails. It is generally defined as the study of how the nervous system develops‚ its structure and the functions it carries out. Neuroscientists study the brain and how it impacts on human beings behavior and cognitive functions. The study also looks at what occurs when things don’t go right. It aims to understand

Most types of Porphyria are inherited and the risks of developing a Porphyria disease and passing it on is pretty much determined by what the specific signs and symptoms are depending on which of your genes is abnormal. Two main types of Porphyria affect two totally different things. One affects the skin‚ and the other affects the nervous system. People with the skin type called‚ Porphyria Cutanea Tarda (PCT) is the

Question 6 Voluntary movements‚ such as writing with a pencil‚ are directed by the somatic nervous system. Question 7 Cortical areas that are NOT primarily concerned with sensory‚ motor‚ or language functions are called association areas.

Chapter 2- Darwin was the first to suggest how evolutionoccurs. Humans belong to the primate family known as hominins. Characteristics that evolved to perform one function but were co-opted to perform another function are called exaptations. Each group of three consecutive nucleotide bases along the strand of messenger RNA is called a codon‚ which instructs the ribosome to add amino acids to the protein being constructed. Subsequent to the nature-nuture issue‚ a second line of thought surrounding

Introduction Three sources of sensory information are used by the nervous system in the maintenance of equilibrium. These are the eyes‚ proprioceptive endings throughout the body and the vestibular portion of the internal ear. In the development of the human body functions‚ the vestibular system is one of the first of the sensory integrative systems to be fully functional. The complete integration of the other sensory systems like vision and proprioception are continued throughout childhood

assumptions do biopsychologists make? Psychologists from the biological approach assume that behaviour and experiences are caused by activity in the nervous system of the body. The things that people think and feel‚ say and do are caused‚ one way or another‚ by electrochemical events occurring within and between the neurones that make up their nervous system‚ particular those in the brain. Many biopsychologists also agree that because the development of the brain is determined (at least partly) by the

How neurons communicate Neurons are the specialized cells which make up the body’s nervous system. These nerve cells process and transmit information from one part of the body to another. For example‚ if you were to touch a candle flame for more than an instant‚ pain nerves also known as receptors that are in your finger would send a message up through your hand and arm to the spinal cord and then to the brain. The brain which in turn records pain and sends the messages back down to various parts
