Study Notes
Human Body Composition
- Oxygen, Carbon, Hydrogen, and Nitrogen make up 96% of the human body's mass.
Biomolecules
- The general name for the class of material that includes biomolecules is organic compounds.
- Most biomolecules are produced within an organism's cells.
- Primary metabolites that are considered biomolecules include carbohydrates, proteins, lipids, and nucleic acids.
Biology Subfields
- Biochemistry and molecular biology are the subfields that study biomolecules and their reactions.
Femur and Lower Limb
- The femur is the longest, heaviest, and strongest bone in the human body.
- The major factor in determining the femoral-tibial angle is the Q-angle, which is the angle formed by the quadriceps muscle and the patella tendon.
- The top of the femur connects to the pelvis at the hip joint in humans.
- In the condition genu valgum (knock knee), the femoral-tibial angle is increased, resulting in the knees angling inward.
- The opposite extreme of genu valgum is genu varum (bow leg), where the femoral-tibial angle is decreased, resulting in the knees angling outward.
