    Study Notes

    Nervous System Anatomy

    • The nervous system constantly sends and receives messages to manage body functions.
    • The brain receives sensory input from the spinal cord and nerves, and controls body functions.
    • The spinal cord provides sensory information to the brain.
    • Nerves are bundles of nerve cells (neurons) that transmit impulses between the body and brain.
    • The brain organizes and processes information for the body, including memory and coordination.
    • The cerebrum is the largest part of the brain, responsible for problem-solving, memory, and reasoning.
    • It's divided into two hemispheres: the right controls the left side of the body, the left controls the right.
    • Each hemisphere has four lobes:
      • Frontal lobes (motor area): responsible for motor functions and higher-order functions like reasoning and memory.
      • Parietal lobes: responsible for sensory impulses (pain, touch, temperature) and visual perception.
    • The cerebellum coordinates muscle movements and is located below the cerebrum.
    • The brain stem controls involuntary processes like breathing, digestion, and blood circulation. It's divided into the midbrain, pons, and medulla oblongata.
    • The medulla oblongata becomes the spinal cord responsible for heart rate, breathing, and blood pressure functions.

    Spinal Cord

    • The spinal cord is the major communication pathway between the brain and the peripheral nervous system.
    • It's a series of 31 pairs of nerves that run down the spine.
    • It carries information to and from the brain regarding the body's internal and external conditions.
    • Ascending nerve tracts carry information from the body's muscles and glands to the brain.
    • Descending nerve tracts deliver messages from the brain to the muscles and glands.

    Nerves

    • Nerves are bundles of nerve cells (neurons).
    • Neurons are specialized cells that send and receive messages.
    • Neurons have a cell body (soma) with a nucleus, dendrites that receive signals, and axons that transmit signals.
    • Signals travel across synapses, gaps between neurons.
    • There are three types of neurons: sensory, motor, and interneurons.
      • Sensory neurons carry information from sensory receptors to the CNS.
      • Motor neurons carry signals from the CNS to muscles and glands.
      • Interneurons connect sensory and motor neurons within the CNS.

    Brain and Nervous System Functions

    • The cerebellum coordinates muscle movements.
    • The hypothalamus regulates bodily functions like sleep, thirst, hunger, and body temperature.
    • The thalamus is a relay center for sensory information.
    • The midbrain relays signals between the spinal cord and brain/cerebellum.
    • The pons connects the cerebellum to the cerebrum and to other parts of the brain stem.

    The 5 Senses

    • The 5 senses are sight, sound, smell, taste, and touch which allow interaction with the environment
    • Specialized receptors in the sensory organs translate sensory stimuli into electrical signals which travel through the nervous system
    • The nervous system and sensory organs work together for processing sensory data for interpreting and responding to the environment

    Impulses

    • Nerve impulses transmit information between body parts and the brain.
    • They move through a chain of chemical events, starting from dendrites receiving impulses to axons sending them.
    • Synapses are where nerve impulses move from one neuron to another.
