Study Notes
Respiratory System Structures
-
Palate:
- Divides the nasal cavity from the oral cavity.
- Consists of the hard palate (anterior) and soft palate (posterior).
-
Hyoid Bone:
- U-shaped bone in the neck that supports the tongue.
- Not directly connected to other bones; serves as an attachment point for muscles.
-
Thyroid Gland:
- Butterfly-shaped gland located in the front of the neck.
- Produces hormones that regulate metabolism, growth, and development.
-
Trachea:
- Also known as the windpipe; a tube that connects the larynx to the bronchi.
- Reinforced with C-shaped cartilage rings to maintain its structure and prevent collapse.
-
Primary Bronchi:
- Two main branches of the trachea leading to the lungs.
- Right bronchus is shorter and wider than the left, corresponding to lung anatomy.
-
Secondary Bronchi:
- Branches off from the primary bronchi, leading into each lobe of the lungs.
- There are three on the right (corresponding to three lobes) and two on the left.
-
Bronchiole:
- Smaller branches of the bronchi, leading to the alveoli where gas exchange occurs.
- Lacks cartilage and has a smooth muscle layer, allowing for regulation of airflow.
