Do Now: 02/15 -19 On your own sheet of paper: Predict how well you did on the Unit 5 Exam. How does this compare to your grade for Unit 4?

Unit 5 Test ONo test corrections, so why should we reflect on what we missed? O These questions will likely be on the final and on the CAST test! O Unlike prior years the CAST now counts for 20% of your second semester grade.

Reflection Guide OFollow the directions to complete the handout. OMake sure you completely answer the questions on the back!

Unit 6: Muscle System uary 15 or 19, 2013 Muscle System: Skeletal Muscle Function: 1. list out the three purposes of the muscular system 2. 3. Structure: Composed of connective tissue, muscle tissue, nervous tissue

Connective Tissue O Many muscles can be at the same location in the body. O _________- is the connective tissue separates muscles and holds it in position

Muscle Tissue O The anatomy of a muscle consists of smaller and smaller bundles of different things. O ______-bundles of muscle fibers that make up a muscle O Myofibril- bundles of protein fibers that make up a muscle fiber O Muscle fiber- the basic unit of a muscle made of _____

Myofibril Anatomy A myofibril is made of alternating strands of thick and thin protein that don’t go all of the way down the myofibril. Two components: O Myosin: O Actin: Sarcomere: the repeating unit of a myofibril that goes from Z line to Z line Connect: What is the Z line?

So what does that look like? Fascicle Muscle Myofibril Muscle fiber

On your notes O Put the following in order from smallest to largest: O Muscle, Muscle fibers, Myofibrils, Fascicles, Actin and Myosin

Practice O Complete the following handout O Begin answering Chapter 8 “Check your recall” questions 1 -14 O These questions go into great detail that we did not cover during notes. O Use your textbook to explore the additional structures of skeletal muscle, and the way in which it functions
