PSY290H5 Lecture Notes - Autonomic Nervous System, Peripheral Nervous System, Spinal Nerve
Document Summary
Focus: how the nervous and endocrine systems affect behavior. Pns-peripheral nervous system: somatic and autonomic: sensory and motor nerves going to and from the cns. Endocrine system: different secretory glands: pituitary, adrenal, gonads, thyroid, Why are we interested in neuroanatomy: structure and function are two sides of the same coin, an object s structure imposes physical constraints on its function, neuroanatomy is best understood within a conceptual framework of the structure-function relationship. Neuroanatomy - study of the nervous system s structure: many levels of description, gross neuroanatomy - general structures and connections visible to the naked eye, fine neuroanatomy (microscopic) organization of neurons and their connections. Evolution of the nervous system: properties of the nervous system: irritability (sensory) , conductivity (within central), contractability (motor, with evolution of ns there has occurred increasing. Division of labor within ns so different parts play different roles. Centralization of control, so is development of integration within central area.
