PPT-1. Neurons 6.6: Animals have nervous systems that detect external and internal signals,

All About Neurons Neurons are highlyspecialized cells used by the nervous system to detect signals and transmit them to other neurons or response effectors muscles or glands Neuron Anatomy. Mr. E Murphy. Strange fact. A newborn baby's brain grows almost 3 times during the course of its first year. . Objectives. Identify the importance of the nervous system in humans. Know the difference between the CNS and the PNS. Grinsteinner. . Jacob . McGoogan. Functions of the System. Movement. The control room for all muscle contractions. Senses. Taste. Touch. The nervous system allows us to observe and react to changes in our environment. Peripheral Nervous System. Autonomic Nervous System. Allied Health I. Central Nervous System. Communication and coordination system of the body. Seat of intellect and reasoning. Consists of the brain, spinal cord, and nerves. The Nervous System: Communication. Neurons are masses of nerve cells that transmit information. Three main components:. (1) Cell Body – contains the nucleus and two extensions. (2) Dendrites – shorter, more numerous, receive information. Brain. Spinal Cord. Nerves. Vocabulary to Know . Homeostasis. The regulation of steady, life-maintaining conditions inside an organism, despite changes in its environment . Nerve Cells . Neurons. Basic functioning units of the nervous system . The Nervous System Good Morning… Bell Ringer #1: Reflect back over winter break . Bell Ringer #2 Review your notes from last class. Answer the following question using those notes: How did your nervous system help you conduct the activity you did in the computer lab (red light/green light activity)?

Once the teacher gives the signal, the start person will pass the object to their right. Chapter 11 and 12. Intro Animation. . 2. In the Biology 20 course, you studied some of the major body systems in the context of achieving homeostasis.. Homeostasis. : the process by which a constant internal environment is maintained despite changes in the environment.. is the main component of the two parts of the . nervous system. ; the . brain. and . spinal cord. of the . central nervous system. (CNS), and the branching peripheral nerves of the . peripheral nervous system. THE AUTONOMIC NERVOUS SYSTEM. The autonomic nervous system (ANS) is a motor or efferent system which connects the central nervous system with all smooth muscle, cardiac muscle and gland cells of the body.. Central nervous system comprises the brain and the spinal cord with nervous tissue making up the system. This system is the most intricate system in human body.. The nervous tissue consists of rich network of billions of nerve cells in both the CNS and PNS . Human nervous system two major parts: central nervous system and peripheral nervous system.

Mary Kathryn Pearson, Susan Sabatier, and Olivia Johnson. Simple Nervous Systems. In most animals with nervous systems, clusters of neurons perform specialized functions. . Such clustering is absent in the cnidarians, the simplest animals with nervous systems. .
