Chapter 9 Nervous System Nervous System Function: The nervous system is composed of neurons and neuroglia. _____sensory_______ _______receptors______ at the ends of peripheral nerves gather information and convert it into nerve impulses. When sensory impulses are integrated in the brain as _______sensations_______, this is the integrative function of the nervous system. Conscious or subconscious decisions follow, leading to motor functions via ______effectors________

Lab #12. The Nervous system. Sensorimotor transformations. EPPS BIOE 2101 Spring 2016 INTRODUCTION The nervous system “is” you. Nervous cells transform signals from the outside world into “spikes,” voltage changes, or chemical signals, perform transformations on these signals, and then may turn on muscles. Muscles, in turn, cause behavior: a smile, or moving across the room. Your nervous system is responsible for your interaction with the world, from sensing it to acting upon it. |

important and vital role in a human’s beings life from childhood to adulthood. The body is comprised of two systems. Central nervous system (CNS) composes of the brain and the spinal cord. The central nervous system contains about 90% of the neurons our brains needs to function. The central nervous system integrates sensory information and responds accordingly. The peripheral nervous system (PNS) connects the brain and the spinal cord with the rest of the body. This serves as a communication relay

NERVOUS SYSTEM The nervous system is the complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. CENTRAL NERVOUS SYSTEM The Central NS is made up of the brain and spinal cord BRAIN The brain lies within the skull and is shaped like a mushroom. The brain consists of four principal parts: * the brain stem * the cerebrum * the cerebellum * the diencephalon The brain weighs approximately 1.3 to 1.4 kg. It

The nervous system has three main organs that Zaphera needs to function and keep her body at the right homeostasis (brain, spinal cord, and nerves). The principle of the nervous system is that it produces action potentials (nerve impulses) to control the bodies functions; identifies changes in bodies internal and external surroundings, deciphers changes, and reacts by bringing about compressions or glandular emissions. The sensory system is one of the smallest body frameworks yet it is the most complex

The brain is the central part of central nervous system in all animals. It is composed a many different subunits that work together to help the animal function properly. An important part is the cerebrum, which is “responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body.” This is composed of the four lobes, the frontal, parietal, occipital, and temporal lobes. The frontal lobes are involved in moving and thinking

The nervous system has two parts known as the central and peripheral nervous systems. While the CNS include the brain and the spinal cord the PNS are the sensory neurons and nerves that connect them together. The human central nervous system is made up of the spinal cord and brain. The nerve cells are working between the brain. The spinal cord acts as a signal between the brain and the rest of the body and it controls the musculoskeletal reflexes without help from the brain. The brains responsibility

The brain and spinal cord have the vital job of controlling every bodily function thus controlling every body system. Two systems which they interact with are the endocrine and respiratory system. Central Nervous System’s Interactions with the Endocrine System The endocrine system sends hormones into the blood, sending messages throughout the body. This role is much like the central nervous system’s, which sends messages throughout the body by neuron synapse. The hypothalamus is a tiny collection

The autonomic nervous system is part of nervous system that regulates the body’s unconscious actions. It controls the internal organs of the body, and its in charge of metabolism, cardiovascular activity, temperature regulation, digestion. The autonomic nervous system is divided into sympathetic and parasympathetic nervous system. Sympathetic Nervous System increase heart rate and metabolic rate. It deals with the response to stress and danger by releasing epinephrine and norepinephrine. The parasympathetic

central nervous system can be compared to the air traffic control tower of a large international airport. Just as this main tower directs and controls all incoming and outgoing flights. The central nervous system is the control center of our body, it sends information out and interprets things our body senses. Regulating, controlling and coordinating incoming and outgoing impulses, thoughts, and feelings via nerves. Functionally, the nervous system can be divided into the central nervous system (controls
