Spinal cord collection of neurons and supportive

This preview shows page 5 - 9 out of 9 pages.

Spinal cord: collection of neurons and supportive tissue running from the base of the brain down the center of the back, protected by a column of bones (the spinal column). Peripheral NS Somatic NS: The subdivision of the PNS that connects to sensory receptors and to skeletal muscles; sometimes called the skeletal nervous system.

Autonomic NS: The subdivision of the PNS that regulates the internal organs and glands. Sympathetic Crisis management center Fight or flight Parasympathetic Nutrition and energy conservation Outer structures of the brain AND their functions: cerebral cortex, meninges, right and left hemispheres, corpus callosum, sulci, gyri, motor and somatosensory strips 4 lobes of the brain and their locations AND their major functions Frontal Lobes Front of the brain Functions Planning Memory search Fine Motor control Reasoning Executive Functions Parietal Lobes - Top, rear of the brain Functions include Attention Spatial Location Motor control Somatosensory cortex (body senses) Occipital Lobes At the back of the head Functions include: many aspects of vision Temporal Lobes In front of ears Functions Hearing Memory

The left temporal lobe Language processing Language comprehension Inner brain structures AND their functions: Mid Brain or Limbic System--contains: Amygdala Hippocampus Thalamus Hypothalamus Pituitary Gland Brain Stem: Hindbrain- contains Medulla, Cerebellum, Pons, Reticular Activating System and their functions Parts and functions of the Peripheral Nervous System: 1.) Somatic Motor Somatosensory 2.) Autonomic a. sympathetic b. parasympathetic Endocrine System: definition of hormones definition of endocrine glands Different techniques for observing the brain AND how they work: EEG, CT, MRI, PET, fMRI The effects of alcohol on the brain and behavior His and her’s brains Monozygotic and Dizygotic twins Chapter 3: Sensation and Perception Definitions of sensation and perception : Sensation- the awareness of properties of an object or an event when a sensory receptor is stimulated Perception- the act of organizing and interpreting sensory input as signaling a particular object or event Transduction : the process of converting physical energy into electrochemical impulses in the nervous system Absolute threshold : stimulation necessary to detect presence 50% of the time Just noticeable difference : minimum change needed to detect difference Weber’s Law : to notice difference a constant magnitude of change

sensory receptors : specialized neurons that convert physical energy from the environment or the body into electrical energy that can be transmitted as nerve impulses to the brain Doctrine of specific nerve energies : different sensory modes exist because signals received by the sense organs stimulate specific nerve pathways leading to specific areas of the brain, a sensory organ will produce only one type of output regardless of the way it is stimulated sensory adaptation

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
