, Head and Neck
1. Q: Describe the unique aspects of the lymphatic drainage of the head and neck.
A: Lymph from the head and neck drains primarily into superficial and deep cervical
nodes, with jugulodigastric nodes acting as major collection points for head
lymphatics. Lymph from the tongue and tonsils drains to nodes that ultimately reach
the deep cervical chain, while the thyroid drains directly into prelaryngeal,
pretracheal, and paratracheal nodes.
2. Q: Explain the arterial supply to the brain and identify key anastomoses.
A: The brain receives blood from the internal carotid arteries and vertebral arteries,
which form the Circle of Willis at the brain's base. Key anastomoses include
connections among the anterior cerebral arteries and posterior cerebral arteries
through the anterior and posterior communicating arteries.
3. Q: What is the functional significance of the cribriform plate?
A: The cribriform plate of the ethmoid bone allows the passage of olfactory nerve
filaments from the nasal cavity to the olfactory bulbs, enabling the sense of smell. It is
also a potential route for infection spread from the nasal cavity to the cranial cavity.
