An Introduction to the Nervous System The Nervous System – Includes all neural tissue in the body – Neural tissue contains two kinds of cells 1.Neurons » Cells that send and receive signals 2.Neuroglia (glial cells) » Cells that support and protect neurons

An Introduction to the Nervous System Organs of the Nervous System – Brain and spinal cord – Sensory receptors of sense organs (eyes, ears, etc.) – Nerves connect nervous system with other systems

12-1 Divisions of the Nervous System Anatomical Divisions of the Nervous System – Central nervous system (CNS) – Peripheral nervous system (PNS)

12-1 Divisions of the Nervous System The Central Nervous System (CNS) – Consists of the spinal cord and brain – Contains neural tissue, connective tissues, and blood vessels – Functions of the CNS are to process and coordinate: Sensory data from inside and outside body Motor commands control activities of peripheral organs (e.g., skeletal muscles) Higher functions of brain intelligence, memory, learning, emotion

12-1 Divisions of the Nervous System The Peripheral Nervous System (PNS) – Includes all neural tissue outside the CNS – Functions of the PNS Deliver sensory information to the CNS Carry motor commands to peripheral tissues and systems

12-1 Divisions of the Nervous System The Peripheral Nervous System (PNS) – Nerves (also called peripheral nerves) Bundles of axons with connective tissues and blood vessels Carry sensory information and motor commands in PNS – Cranial nerves — connect to brain – Spinal nerves — attach to spinal cord

12-1 Divisions of the Nervous System Functional Divisions of the PNS – Afferent division Carries sensory information From PNS sensory receptors to CNS – Efferent division Carries motor commands From CNS to PNS muscles and glands

12-1 Divisions of the Nervous System Functional Divisions of the PNS – Receptors and effectors of afferent division Receptors – Detect changes or respond to stimuli – Neurons and specialized cells – Complex sensory organs (e.g., eyes, ears) Effectors – Respond to efferent signals – Cells and organs

12-1 Divisions of the Nervous System Functional Divisions of the PNS – The efferent division Somatic nervous system (SNS) – Controls voluntary and involuntary (reflexes) muscle skeletal contractions

12-1 Divisions of the Nervous System Functional Divisions of the PNS – The efferent division Autonomic nervous system (ANS) – Controls subconscious actions, contractions of smooth muscle and cardiac muscle, and glandular secretions – Sympathetic division has a stimulating effect – Parasympathetic division has a relaxing effect
