9 Peripheral Nervous System (PNS) The sensory and motor nerves that connect the central nervous system to the rest of the bodyPeripheral means “outer region”The system is subdivided into the somatic and autonomic nervous systems.
13 Autonomic Nervous System The division of the peripheral nervous system that controls the glands and muscles of the internal organsMonitors the autonomic functionsControls breathing, blood pressure, and digestive processesDivided into the sympathetic and parasympathetic nervous systems
65 III. The Forebrain Areas of the forebrain control thought and reason. There are five main regions of the forebrain to study:ThalamusHypothalamusAmygdalaHippocampusThe Cerebral Cortex
66 On top of the hindbrain is the THALAMUS The THALAMUS receives sensory input from all of the senses except smell, and routes it to the proper area of the brain for processingThe THALAMUS also helps to control the electrical currents in the brain
83 The CEREBRAL CORTEX is the intricate, wrinkled covering of the brain (FISSURES) (actually a bump is a gyrus and a groove is a sulcus – but that’s a bit too much info…)In addition to interneurons, it contains GLIAL CELLS, which guide neural connections, provide nutrients to myelin, and mop up neurotransmitters
119 Plasticity The ability of the brain tissue to take on new functions Greatest in childhoodImportant if parts of the brain are damaged or destroyedGo to the next slide to see a video about brain plasticity!
