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;

CS306- INTELLIGENT SYSTEMS Part – A 1. There are well-known classes of problems that are intractably difficult for computers‚ and other classes that are provably undecidable. Does this mean AI is impossible? (2) No‚ it means that AI systems should avoid trying to solve intractable problems. Usually this means they can only approximate optimal behavior. Notice that even humans do not solve NP- complete problems. Sometimes they are good at solving specific instances with a lot of structure

-We have 2 parts in our nervous system: The central nervous system (CNS) is the nerves in our brain and spinal chord. The peripheral nervous system (PNS) is a network of nerve cells in the rest of our body. -Our nervous system detects stimuli and allows us to react to them. -Stimulus: a change‚ action or occurrence in the environment that can cause an organism to respond. Eg. Light‚ noise‚ pressure… How do we detect stimuli? -We have sensory organs that detect particular stimuli eg. Skin What

Reproductive System What is it? The reproductive system is a collection of organs that work together for the purpose of producing a new life The major organs of the reproductive system include the external genitalia and internal organs‚ including gonads that produce gamete‚ which is a cell that fuses with another cell during conception in organisms that reproduce sexually. Substances such as fluids‚ hormones‚ and pheromones are also important to the effective functioning of the reproductive system What

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

Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth
