If the spinal cord was severed where it joins the brain stem, what effect would it have on respiration?

Explanation

### Step-by-Step Solution:

1. **Understanding the Structure**: The spinal cord is a vital part of the central nervous system and connects the brain to the rest of the body. It runs down the vertebral column and ends at the level of the first or second lumbar vertebra.

2. **Location of Severing**: If the spinal cord is severed at the junction where it meets the brainstem, this is a critical area because the brainstem contains important centers that regulate vital functions, including respiration.

3. **Role of the Brainstem**: The brainstem, particularly the medulla oblongata, is responsible for controlling automatic functions such as breathing. It sends signals down the spinal cord to the nerves that innervate the respiratory muscles.
