Study Notes
Triangles of the Neck
- The submandibular (Digastric) triangle is bounded superiorly by the body of the mandible.
- The floor of the submandibular (Digastric) triangle is formed by the mylohyoid muscle and the anterior belly of the digastric muscle.
- The contents of the submental triangle include the submental lymph nodes, fatty tissue, and small veins that drain into the facial vein.
- The boundaries of the carotid triangle are formed by the sternocleidomastoid muscle, the posterior belly of the digastric muscle, and the omohyoid muscle.
- The floor of the muscular triangle is formed by the omohyoid muscle and the sternothyreoideus muscle.
Protein Structure
- The primary structure of a protein is determined by the sequence of amino acids in the polypeptide chain.
- Genes play a crucial role in determining the primary structure of a protein by encoding the sequence of amino acids.
- The primary structure of a protein is significant because it determines the overall 3D shape and function of the protein.
- A disulfide bond is a covalent bond between two cysteine residues that helps to stabilize the tertiary structure of a protein.
- A defect in the primary structure of a protein can lead to abnormal protein function, misfolding, and aggregation, which can cause various diseases.
