    Study Notes

    Understanding the Autonomic Nervous System

    • The module discusses the structure and function of the autonomic nervous system (ANS) and its sympathetic and parasympathetic divisions.
    • The ANS is compared to the somatic division of the peripheral nervous system (PNS).
    • The ANS has a preganglionic neuron, autonomic ganglion, and postganglionic neuron in its efferent pathway.
    • The postganglionic neurons in ANS pathways are either sympathetic (excitatory) or parasympathetic (inhibitory) in function.
    • Autonomic neurons are classified as cholinergic (releasing acetylcholine) or adrenergic (releasing norepinephrine).
    • The sympathetic response is the "fight or flight" response, while the parasympathetic response is the "rest and digest" response.
    • The somatic nervous system contains sensory and motor neurons involved in conscious perception and voluntary movements.
    • The autonomic nervous system regulates visceral activities and receives sensory input from somatic and special sensory neurons.
    • Most autonomic responses cannot be consciously altered or suppressed.
    • All autonomic motor pathways consist of two motor neurons in a series, releasing acetylcholine or norepinephrine.
    • The module references specific pages and figures from the OpenStax A&P textbook.
    • The module also provides self-test resources and additional online educational resources for further study.

    Anatomy and Physiology Basics

    • Anatomical position is a standardized method for observing and imaging the body, involving a standing erect subject with arms at the side, palms forward, and flat feet.
    • Directional terms are used to precisely locate body parts relative to one another, including dorsal, superior, medial, ventral, inferior, lateral, and proximal.
    • Body planes, including sagittal, frontal, transverse, and oblique, are used to divide the body into specific areas for analysis and imaging.
    • Body cavities, such as the dorsal and ventral cavities, protect and support internal organs, with the ventral cavity further subdivided into thoracic and abdominopelvic cavities.
    • The abdominopelvic cavity can be divided into nine regions or quadrants to locate abnormalities or specific organs.
    • Elements, the fundamental materials of matter, are composed of chemical elements with specific symbols, and the human body is predominantly made up of oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
    • Atoms are the smallest quantities of elements, consisting of a nucleus with protons and neutrons, and negatively charged electrons in different energy levels.
    • Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons, and radioactive isotopes emit energy.
    • Anatomical images and figures are used to illustrate anatomical positions, directional terms, body planes, body cavities, and regions of the body for study and reference.
    • The anatomical position, directional terms, body planes, and body cavities are fundamental concepts in anatomy and physiology, providing a standardized framework for understanding and studying the human body's structure.
    • The regions of the body and the localized areas within each region can be identified and studied using the anatomical position, directional terms, body planes, and body cavities, providing a comprehensive understanding of human anatomy.
    • Understanding the structure of atoms and isotopes is crucial for comprehending the elemental composition of the human body and the biochemical processes that occur within it.

    • The abdominopelvic cavity can be divided into nine regions or quadrants to locate abnormalities or specific organs.
    • Elements, the fundamental materials of matter, are composed of chemical elements with specific symbols, and the human body is predominantly made up of oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
    • Atoms are the smallest quantities of elements, consisting of a nucleus with protons and neutrons, and negatively charged electrons in different energy levels.
    • Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons, and radioactive isotopes emit energy.
    • Anatomical images and figures are used to illustrate anatomical positions, directional terms, body planes, body cavities, and regions of the body for study and reference.
    • The anatomical position, directional terms, body planes, and body cavities are fundamental concepts in anatomy and physiology, providing a standardized framework for understanding and studying the human body's structure.
    • The regions of the body and the localized areas within each region can be identified and studied using the anatomical position, directional terms, body planes, and body cavities, providing a comprehensive understanding of human anatomy.
    • Understanding the structure of atoms and isotopes is crucial for comprehending the elemental composition of the human body and the biochemical processes that occur within it.
