Task 211.4.4-01-05, 07-09, 11 Nervous System Organization of Nerve Tissue Lab Exercise 1: The Multipolar Neuron A. What is the function of a neuron? Neurons carry and transmit electrical impulses generated by both internal and external stimuli. B. What is the difference between a neuron and a nerve? Neurons are the cells that exchange messages from the internal and external environments. Nerves consist of many neurons that transmit different

Chapter 12 The Nervous System All neural tissue in the body Neurons send(motor) and receive (sensory) signals Neuroglia support and protect neurons 1. Central Nervous System- (CNS) brain and spinal cord; process and coordinate sensory (internal and external data) motor commands(control peripheral organs), higher function of brain ( intelligence, memory, learning and emotions) 2. Peripheral Nervous System- (PNS) a;; neural tissue outside the CNS. Delivers sensory( input) info to the CNS

much earlier. In 2006, there were 26.6 million sufferers worldwide. Alzheimer's is predicted to affect 1 in 85 people globally by 2050. https://www.youtube.com/watch?v=XFcmuRgOWQU Parkinson’s disease is a degenerative disorder of the central nervous system. The motor symptoms of Parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain; the cause of this cell death is unknown. Early in the course of the disease, the most obvious symptoms

The major structures that hormones can do are they promote or inhibit the generation of nerve impulses. They can also have the same molecules that are used in both endocrine system and the nervous system. 4. What are functional and structural plasticity? The functional plasticity is the brain’s ability to shift functions from damaged to undamaged brain areas. This means that if a person is damaged from the brain, stroke, or accident

The Nervous System and Special Senses Abstract This paper contains a brief discussion on the overview of the nervous system and the organs that play a major role in the system. It goes into further detail of the nervous system by separating into the central nervous systems and its functions, the peripheral nervous system and its two branches under the system; including what it is responsible for and briefly how it works. The paper then discusses the special senses. It focuses on the eyes

The Central Nervous System The central nervous system consists of the brain and spinal cord.The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus .The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla. Most the time the midbrain, pons, and medulla are called to go together as the brainstem.The cerebrum or cortex is the largest part of the human brain

he function of nervous system is to coordinate the activities of our body. It is the control system for all our actions, thinking and behaviour. The nervous system helps all other systems of our body to work together.The nervous system is like a manager inside our body. Its job is to control and coordinate the parts of our body so that they work together, doing their job at the right time. Our nervous system coordinates muscles so that we can do things which need thinking like reading, writing

Sensory and Nervous System The sensory and nervous system becomes much more complex as one moves through the phyla of the animal kingdom. From phylum placozoa to phylum Chordata, the sensory and nervous systems gradually get more and more involved. Phylum Placozoa consists of only one known species, Trichoplax adhaerens (Nielson, 2001, p. 48). Made up of only a few thousand cells, and generally only 2 mm across, this species does not even seem as though it should be considered part of the

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________
