Termini in questo insieme (20)

  • What are the levels of structural organization in the human body?

    The levels include chemical, cellular, tissue, organ, organ system, and organism levels.

  • What is the anatomical position?

    Body standing upright, ventral side facing you, palms up, with right and left referring to the organism's perspective.

  • Define the directional term 'Superior' (cranial).

    Superior means toward the head or upper part of a structure.

  • Define the directional term 'Inferior' (caudal).

    Inferior means away from the head or toward the lower part of a structure.

  • What does 'Anterior' (ventral) mean in anatomical terms?

    Anterior means toward the front or belly side of the body.

  • What does 'Posterior' (dorsal) mean in anatomical terms?

    Posterior means toward the back or spine side of the body.

  • Explain the terms 'Medial' and 'Lateral'.

    Medial means toward the midline of the body; Lateral means away from the midline.

  • What do 'Proximal' and 'Distal' refer to?

    Proximal means closer to the point of attachment; Distal means farther from the point of attachment.

  • What is the difference between 'Superficial' and 'Deep'?

    Superficial means toward or on the surface; Deep means away from the surface, internal.

  • What are the axial and appendicular regions of the body?

    Axial refers to the head, neck, and trunk; Appendicular refers to the limbs or appendages.

  • Name the major body planes used in anatomy.

    Sagittal, Frontal (coronal), Transverse (horizontal), and Oblique planes.

  • What is the sagittal plane?

    A vertical plane dividing the body into right and left parts; midsagittal divides equally.

  • What is the frontal (coronal) plane?

    A vertical plane dividing the body into anterior (front) and posterior (back) parts.

  • What is the transverse (horizontal) plane?

    A horizontal plane dividing the body into superior (upper) and inferior (lower) parts.

  • What are the dorsal body cavities and what do they contain?

    The cranial cavity houses the brain; the vertebral (spinal) cavity houses the spinal cord.

  • What are the ventral body cavities and their subdivisions?

    The thoracic cavity (pleural cavities for lungs, mediastinum with pericardial cavity for heart) and the abdominopelvic cavity (abdominal and pelvic cavities).

  • What membrane lines the thoracic and abdominopelvic cavities?

    The serous membrane: pleura lines thoracic cavity; peritoneum lines abdominopelvic cavity.

  • What are the four abdominopelvic quadrants?

    Right upper, left upper, right lower, and left lower quadrants used to locate organs.

  • What are the nine abdominopelvic regions?

    Right and left hypochondriac, epigastric, right and left lumbar, umbilical, right and left iliac (inguinal), and hypogastric (pubic) regions.

  • What is the difference between visceral and parietal serous membranes?

    Visceral membranes cover organs; parietal membranes line the body cavity walls.
