Neurons: cells that send and receive signals 2. Neuroglia (glial cells): cells that support and protect neurons Organs of the Nervous system - CORRECT ANSWER Brain and Spinal cord Sensory receptors of sense organs (eyes, ears, etc) Nerves connect nervous system with other systems Central Nervous system (CNS) - CORRECT ANSWER Consists of the spinal cord and brain Functions of the CNS - CORRECT ANSWER Process and coordinate: Sensory data from inside and outside body Motor commands control activities of peripheral organs Higher functions of brain: intelligence, memory, learning, emotion Peripheral Nervous sytem (PNS) - CORRECT ANSWER Includes all neural tissue outside the CNS Functions of the PNS - CORRECT ANSWER Deliver sensory information to the CNS Carry motor commands to peripheral tissues and systems Afferent and Efferent division Peripheral nerves - CORRECT ANSWER Nerves of the PNS Bundles of axons w/ connective tissues and blood vessels Carry sensory information and motor commands in PNS Cranial and Spinal Nerves Cranial vs Spinal Nerves - CORRECT ANSWER Cranial nerves: connect to brain Spinal nerves: attach to spinal cord Afferent Division (PNS) - CORRECT ANSWER Carries sensory information From PNS sensory receptors to CNS Efferent Division (PNS) - CORRECT ANSWER Carries motor commands From CNS to PNS muscles and glands Receptors of afferent division - CORRECT ANSWER Detect changes or respons to stimuli Neurons and specialized cells Complex sensory organs (e.g. eyes, ears) Effectors of afferent division - CORRECT ANSWER Respond to efferent signals Cells and organs Somatic Nervous system (SNS) - CORRECT ANSWER Efferent division Controls voluntary and involuntary muscle contractions - (Shivering and reflexes) Autonomic Nervous system (ANS) - CORRECT ANSWER Controls subconscious actions, contractions of smooth muscle and cardiac muscle, and glandular secretions
