    Study Notes

    Human Anatomy

    Overview

    • Study of the structure of the human body.
    • Involves various systems, organs, and tissues.

    Major Body Systems

    1. Skeletal System

      • Composed of bones, cartilage, and joints.
      • Provides structure, support, and protection for internal organs.
      • Key components: skull, vertebrae, rib cage, limbs.
    2. Muscular System

      • Contains all muscles in the body.
      • Responsible for movement, posture, and heat production.
      • Types: skeletal (voluntary), smooth (involuntary), cardiac (heart).
    3. Circulatory System

      • Comprises the heart and blood vessels.
      • Responsible for transporting blood, nutrients, gases, and waste.
      • Key components: arteries, veins, capillaries.
    4. Respiratory System

      • Facilitates gas exchange: oxygen intake and carbon dioxide removal.
      • Key structures: nasal cavity, pharynx, larynx, trachea, lungs.
    5. Digestive System

      • Breaks down food for nutrient absorption.
      • Key organs: mouth, esophagus, stomach, intestines, liver, pancreas.
    6. Nervous System

      • Controls body functions through electrical signals.
      • Divided into central (brain and spinal cord) and peripheral (nerves) systems.
    7. Endocrine System

      • Glands that secrete hormones to regulate bodily functions.
      • Key glands include pituitary, thyroid, adrenal, and pancreas.
    8. Reproductive System

      • Responsible for producing offspring.
      • Male components: testes, penis; Female components: ovaries, uterus.
    9. Integumentary System

      • Consists of skin, hair, nails, and associated glands.
      • Protects body, regulates temperature, and provides sensory information.
    10. Lymphatic/Immune System

      • Part of the immune defense and fluid balance.
      • Composed of lymph nodes, lymph vessels, and spleen.

    Anatomical Terminology

    • Anatomical Position: Body standing upright, facing forward, arms at sides, palms facing forward.
    • Directional Terms:
      • Superior: above
      • Inferior: below
      • Anterior: front
      • Posterior: back
      • Medial: toward the midline
      • Lateral: away from the midline
      • Proximal: closer to the trunk
      • Distal: farther from the trunk

    Planes of the Body

    • Sagittal Plane: Divides body into left and right.
    • Frontal (Coronal) Plane: Divides body into anterior and posterior.
    • Transverse Plane: Divides body into superior and inferior.

    Basic Tissue Types

    1. Epithelial Tissue: Covers body surfaces and lines cavities.
    2. Connective Tissue: Supports and binds other tissues (e.g., bone, blood).
    3. Muscle Tissue: Responsible for movement (skeletal, cardiac, smooth).
    4. Nervous Tissue: Composed of neurons and glial cells, facilitates communication.

    Developmental Anatomy

    • Study of structural changes from fertilization to adulthood.
    • Involves embryology (development before birth) and postnatal changes.

    These notes cover the foundational aspects of human anatomy, providing a structure for further detailed study.

    Overview of Human Anatomy

    • Focuses on the structure and organization of the human body.
    • Encompasses various interconnected systems, organs, and tissues that function collectively.

    Major Body Systems

    • Skeletal System

      • Comprised of bones, cartilage, and joints, providing essential support and protection.
      • Key structures include the skull, vertebrae, rib cage, and limbs.
    • Muscular System

      • Contains all muscle types, enabling movement and maintaining posture through contraction.
      • Three muscle types:
        • Skeletal (voluntary control)
        • Smooth (involuntary control; found in internal organs)
        • Cardiac (involuntary control; heart)
    • Circulatory System

      • Includes the heart and a network of blood vessels to transport blood and nutrients.
      • Major components are arteries, veins, and capillaries, involved in nutrient and gas exchange.
    • Respiratory System

      • Essential for gas exchange, helping to bring in oxygen and expel carbon dioxide.
      • Key components are the nasal cavity, pharynx, larynx, trachea, and lungs.
    • Digestive System

      • Facilitates the breakdown and absorption of food for nutrient acquisition.
      • Principal organs include the mouth, esophagus, stomach, intestines, liver, and pancreas.
    • Nervous System

      • Manages body functions via electrical signals, coordinating voluntary and involuntary actions.
      • Consists of the central nervous system (brain and spinal cord) and peripheral nervous system (nerves).
    • Endocrine System

      • Composed of glands that release hormones, regulating growth, metabolism, and homeostasis.
      • Major glands include the pituitary, thyroid, adrenal glands, and pancreas.
    • Reproductive System

      • Responsible for production of offspring, varying between male and female structures.
      • Male: testes and penis; Female: ovaries and uterus.
    • Integumentary System

      • Functions as a barrier protecting the body; includes skin, hair, nails, and glands.
      • Regulates temperature and processes sensory information.
    • Lymphatic/Immune System

      • Critical for immune response and maintaining fluid balance in the body.
      • Comprised of lymph nodes, lymph vessels, and the spleen.

    Anatomical Terminology

    • Anatomical Position: Body upright, facing forward with arms at the sides and palms forward.
    • Directional Terms:
      • Superior: Above
      • Inferior: Below
      • Anterior: Front
      • Posterior: Back
      • Medial: Toward the midline
      • Lateral: Away from the midline
      • Proximal: Closer to the trunk
      • Distal: Farther from the trunk

    Planes of the Body

    • Sagittal Plane: Divides the body into left and right sections.
    • Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back) sections.
    • Transverse Plane: Divides the body into superior (upper) and inferior (lower) sections.

    Basic Tissue Types

    • Epithelial Tissue: Covers surfaces and lines cavities, acting as a protective layer.
    • Connective Tissue: Supports and binds other tissues; includes types like bone and blood.
    • Muscle Tissue: Facilitates movement; categorized into skeletal, cardiac, and smooth tissue.
    • Nervous Tissue: Composed of neurons and glial cells, responsible for communication within the body.

    Developmental Anatomy

    • Examines the changes in structure from fertilization to adulthood.
    • Includes the study of embryology (development before birth) and subsequent postnatal changes.
