Study Notes
Anatomical Directions
- Median refers to a body part that is closer to the midline.
- Lateral refers to a body part that is away from the midline.
- Anterior refers to a body part that is towards the front.
- Posterior refers to a body part that is towards the back.
- Proximal refers to a body part that is closer to the point of attachment.
- Distal refers to a body part that is further from the point of attachment.
Cell Division and DNA
- During cell division, chromosomes are formed and carry genetic information.
- DNA plays a role in this process by carrying genetic information.
- Transcription occurs in the nucleus.
- During transcription, a part of the DNA molecule is copied into a complementary RNA molecule.
- mRNA (messenger RNA) carries genetic information from DNA to the ribosomes.
- Editing of mRNA occurs in the nucleus.
- Edited mRNA is transported out of the nucleus through the nuclear pore.
Homeostasis
- Homeostasis refers to the body's ability to maintain a constant internal environment.
- Basic physiological needs necessary to maintain homeostasis include temperature, pH, and blood sugar levels.
- The #1 way that the body controls and maintains homeostasis is through negative feedback.
- The three components involved in negative feedback are the receptor, control center, and effector.
- The control center receives and processes information from the receptor and sends signals to the effector.
Anatomical Terms
- The 'starting point' for all descriptive terms that can be applied to the body is the anatomical position.
Minerals and Their Functions
- Calcium is most often associated with healthy bones and teeth.
- The main role of potassium in the body is to regulate heart rhythm.
Energy and Metabolism
- The process of using fats as energy to maintain life is called ketosis.
- When there are too many ketones produced during fat metabolism with lipids, it can lead to ketoacidosis.
Proteins
- Proteins do not function as a energy source.
- Deoxyribose is the sugar found in DNA.
Enzymes
- Kinases are enzymes responsible for adding or removing phosphate groups.
- The function of hydrolases is to break down molecules using water.
Protein Synthesis
- mRNA (messenger RNA) carries genetic information from DNA to the ribosomes.
- rRNA (ribosomal RNA) makes up a large part of the ribosomes.
- tRNA (transfer RNA) brings amino acids to the ribosomes.
- snRNP (small nuclear ribonucleoprotein) is involved in the editing of mRNA.
