Nervous System Review Sheet 1. List three functions of the nervous system and give a specific example of each. • Reception of stimuli from environment (internal or external) and relay of info to CNS (Sensory division of PNS) – e.g. Receptors in your ear send a signal to the brain when the bell rings. • Integration of stimuli to decide on a response (CNS) – e.g. Your brain receives the signal that the bell is ringing‚ along with signals from your eyes that tell you it is time for class

Biology 3201 1. Unit 1- Maintaining Dynamic Equilibrium II Ch. 12 – The Nervous System (pp. 390-419) 12.1 – Structure of the Nervous System nervous system: a high-speed communication system which delivers information to and from the brain and spinal cord and all over the body. In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

One student has a support system and the other does not. Without a support system for a student not to have would be very hard on a student because you wouldn’t have people to fall back on to push you forward then if you would have if you had the support system. It very important to have a support system because you need someone to fall back on. Relationships are very important for success because without a support system people would not push themselves. Relationships have a positive impact on your

Nervous System Functions of the Nervous System 1. Detect changes and feel sensations 2. Initiate responses to changes 3. Organize and store information Divisions 1. Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1. Neuron cell body contains the nucleus; cell bodies are in the CNS or trunk;
