Learning Point 1: Where is it?

Let’s have a quick recap of the sliding filament theory and structure of a muscle. The myofilaments, called actin and myosin, make up the sarcomere. A long row of sarcomeres makes up a muscle fibre or myofibril.

The sarcoplasmic Reticulum surrounds each muscle fibre like a net. You can see it in this image as a blue river around the muscle fibre

Learning Point 2: What is the Sarcoplasmic Reticulum?

Essentially the sarcoplasmic reticulum stores and releases calcium for muscle contractions.

If the words still seem to be a little daunting and confusing then breaking them down can help reinforce the name and the meaning.
Sarco = Muscle
Plasmic = Liquid
Reticulum = Net like structure

TOP TIP: The main thing you need to know for your Level 3 Anatomy and Physiology Exam is that the Sarcoplasmic Reticulum is responsible for the storage and the releasing of calcium; which is important for muscle contractions.
