Sensory Memory

The initial stage of memory where sensory information is briefly held (3-4 seconds). It's like a snapshot of the world around us. We only pay attention to what's interesting or meaningful, and that information then moves to working memory.

Working Memory

The active workspace of our minds where we temporarily hold and process information. It's like the "mental workbench" where we manipulate, organize, and rehearse information. There are verbal and visual components to help us remember.

Episodic Memory

The long-term storage of personal experiences, like your first day of school or a recent vacation. It's about memories that are tied to specific events and time.

Semantic Memory

The long-term storage of general facts and information about the world, like knowing the capital of France or how to ride a bike. Think of it as knowledge that's not specific to a particular event.

Study Notes

Introduction to Human Body

  • Anatomy is the study of the body's structure.
  • Physiology is the study of how the body functions.
  • Dissection is a key method in studying anatomy.

Levels of Organization

  • Chemical: atoms combine to form molecules.
  • Cellular: molecules combine to form cells.
  • Tissue: groups of similar cells working together.
  • Organ: a structure made of different tissue types.
  • System: related organs functioning together.
  • Organismal: all systems working together in a single organism.

Anatomical Terminology

  • Anatomical position: standing erect, facing forward, arms at sides, palms forward.
  • Prone position: lying face down.
  • Supine position: lying face up.

Regional Names of Body

  • Head, neck, trunk, upper limb, lower limb, groin.

Body Planes

  • Sagittal: divides body into right and left.
  • Midsagittal: equal halves.
  • Parasagittal: unequal halves.
  • Frontal: divides into front and back portions.
  • Transverse: divides into upper and lower portions.
  • Oblique: passes through at an oblique angle.

Directional Terms

  • Superior (cranial): towards the head.
  • Inferior (caudal): towards the feet.
  • Anterior (ventral): front of the body.
  • Posterior (dorsal): back of the body.
  • Medial: toward the midline.
  • Lateral: away from the midline.
  • Intermediate: between two structures.
  • Ipsilateral: same side of the body.
  • Contralateral: opposite side of body.
  • Proximal: closer to the origin of a structure.
  • Distal: farther from the origin of a structure.
  • Superficial: closer to the body surface.
  • Deep: farther from the body surface.
  • External: outer part of an organ.
  • Internal: inner part of an organ.

Body Cavities

  • Spaces within the body that house internal organs.
    • Cranial: houses the brain.
    • Vertebral: houses the spinal cord.
    • Thoracic: contains pleural cavities (lungs), pericardial cavity (heart), and mediastinum (other thoracic organs).
    • Abdominopelvic: subdivided into abdominal and pelvic cavities.
      • Abdominal: most of the digestive organs.
      • Pelvic: bladder, reproductive organs, and part of the large intestine.
  • Pleural and pericardial cavities are serous cavities with a lubricating fluid to prevent friction.

Abdominopelvic Quadrants

  • Dividing the abdominopelvic region into four quadrants for localization of pain or medical conditions.

Eleven Systems of the Body

Six Characteristics of Life Processes

  • Metabolism: sum of chemical processes.
  • Responsiveness: ability to detect and respond to environmental changes.
  • Movement: includes whole body, organ, and cellular movement.
  • Growth: increase in size due to cell increase, cell size increase, or material increase.
  • Differentiation: unspecialized cells become specialized cells.
  • Reproduction: formation of new cells or a new organism.
