Definition

Relating to the space surrounding the spinal cord where certain medical treatments can be delivered, such as anesthesia.

Example

Conversation

I heard that some pain medications can be delivered through an intrathecal method.

Really? I didn't know that was an option for pain relief.

Yeah, it goes directly into the spinal canal, which can be more effective.

That sounds interesting; I might look into it if I ever need something stronger.

Root Explanation

Intrathecal → It is formed from "intra-" (meaning within) and "theca" (from Greek "thēkē", meaning case or sheath). The word "intrathecal" refers to something that is administered or occurring within the sheath surrounding the spinal cord.

Memory Tip

Think of 'intra-' meaning 'within' and 'theca' meaning 'sheath' — this helps you remember that 'intrathecal' refers to something that happens within the sheath around the spinal cord.
