Study Notes
Anatomy & Physiology
- Anatomy involves studying the structure and shape of organisms, and how their bodily parts relate to each other.
- Physiology focuses on the function of living organisms and the roles of their various parts.
Matter & Atoms
- Atoms are the smallest units of matter, essential for forming all substances.
- Matter is anything that occupies space and has mass.
Atomic Concepts
- Atomic number represents the number of protons within an atom's nucleus.
- Atomic mass is determined by the total number of protons and neutrons in an atom.
Biological Building Blocks
- Elements consist of pure substances made up of one type of atom, fundamental to all matter.
- Cells are the smallest living units in the body, crucial for structure and function.
- Tissue comprises groups of similar cells that work together to perform specific functions.
- Organs are collections of different tissues that coordinate to perform specialized tasks.
Biological Systems
- Systems are composed of multiple organs working synergistically to perform complex bodily functions.
- Key body systems include integumentary, skeletal, muscular, nervous, and endocrine.
Anatomical Position & Directional Terms
- Superior indicates a position higher or towards the head.
- Inferior refers to a position lower or towards the feet.
- Anterior defines the front part of the body, while posterior indicates the back.
- Medial refers to a position toward the midline, contrasted with lateral, which means away from it.
- Proximal indicates a position closest to the trunk, whereas distal refers to a position farthest from the trunk.
- Superficial describes a location near the surface, while deep indicates a position farther from the surface.
Regional Terminology
- Carpal relates to the wrist, cervical to the neck, costal to the ribs, cranial to the skull, femoral to the thigh, frontal to the forehead, lumbar to the lower back, pelvic to the pelvis, sternal to the sternum, and thoracic to the chest.
Chemical Composition
- Molecules form when atoms bond together, creating larger chemical units.
- Compounds consist of molecules that contain more than one type of element.
- Buffers are chemical systems that help absorb excess acids or bases, maintaining a stable pH.
- Chemical bonds are necessary for atoms to achieve stability, with ionic bonds forming between oppositely charged ions.
- Electrolytes are molecules that disassociate in solution, contributing to the conductivity and balance of bodily fluids.
