Nervous system

1 Central Nervous System Communication As stated by the website, umaine.edu, agenesis of the corpus callosum is a rare birth defect, a lifelong brain abnormality, in which there is a complete or partial absence of the corpus callosum. This occurs when the corpus callosum, which is the band of white matter connecting the two hemispheres in the brain, fails to develop normally, typically during pregnancy. The types of behavioral changes that would occur because of this failure to develop are…

interpret, store and use information. The nervous system is divided into central nervous system (CNS) and peripheral nervous system (PNS). The CNS consists of the brain and spinal cord and they are the decision makers of the body. Sensory information gathering and action transmission occurs in the PNS. The brain consists of approximately 100 billion neurons and it is the smallest building block in the brain. They connect and carry messages to and from the nervous systems. There are different…

The central nervous system is crucial to human function; it consists of the brain, spinal cord and a network of nerves moving to the rest of our body. It controls everything in the body e.g. emotions, senses, responses, reactions, body balance like temperature and heartbeat as well as movement of our muscles and glands. The CNS (Central nervous system) covers the brain and spinal cord where the PNS (Peripheral nervous system) is made up of the nerve fibre’s that branch off from the spinal cord…

The human nervous system is our electrical wiring of the body that transmits signals between different parts of the body. It has two components; the central nervous system and the peripheral nervous system. The nervous system is an intricate part of your body and life that 's made up of two separate systems, the brain, and spinal cord. During prenatal growth, the nervous system experiences many changes to gain its compound structure. The events of this early development include the…

#2 Describe in detail the structure and function of any of the following: the nervous system, the brain, the endocrine system. Include charts with you description if you desire. Simple moments, decisions or reactions all have one thing in common, the brain. The brain is the control center for human’s entire body, giving signals at all times on what to do or how to respond. Nerves that connect your body to the brain are responsible for gather information to give to the spinal cord to give to…

1 Hypothalamus – a small region of the brain that is a major link between the nervous and endocrine system. The hypothalamus controls the autonomic nervous system and regulates body temperature, hunger, thirst, fear, rage, and sexual behavior. The hypothalamus control feeling such as pain, stress, and emotional experiences. (1) 2 Pituitary gland – the “master endocrine gland” because it secretes many hormones that control other endocrine glands. It is a “pea-shaped structure that attaches to…

Michael Phelps, Serena Williams, Usain Bolt and Louis Zamperini have one thing in common: a unique nervous system. What makes an olympic athlete’s brain anatomy different from a regular athlete? What changes take place in their brain and its connecting peripheral nerves? And can anyone become an olympic athlete? The human body is capable of making changes to itself to adapt to different environments and specific tasks. Not only do the muscles in our body change but also our brain and certain…

The nervous system is broken down into two major systems: Central Nervous System and Peripheral Nervous System. We’ll discuss the Central Nervous System first. The Central Nervous System consists of the brain and the spinal cord. The Cerebral Cortex, which is involved in a variety of higher cognitive, emotional, sensory, and motor functions is more developed in humans than any other animal. It is what we see when we picture a human brain, the gray matter with a multitude of folds covering the…

The nervous system makes it possible for animals to know and react to the environment around them. A change or event that evokes a specific functional reaction in an organ or tissue is a stimulus. There can either be an internal or an external stimulus. Internal stimulus being something like hunger or pain, while external is more along the lines of a sound or an odor. The nervous system interprets stimuli and orders other organ systems to respond. The nervous system does so through using sensory…

mechanisms which help explain the cause of various existing neurological and psychiatric diseases (Kotter, 2001). Consequently, the histological study of the nervous system and its components which underlies the understanding of the brain forms the basis and foundation of neuroscientific research (Annese, 2012). Important components of the nervous system include the spinal cord which consists of the grey matter with a butterfly appearance containing ventral and dorsal horns and a central canal…
