Ch. 10 Lab - Muscle System
Name____________________per.___
"Think about the things that you do each day—talking, walking, sitting, standing, and
running—all of these activities require movement of particular skeletal muscles. Skeletal
muscles are even used during sleep. The diaphragm is a sheet of skeletal muscle that has
to contract and relax for you to breathe day and night. If you recall from your study of the
skeletal system and joints, body movement occurs around the
joints in the body. The focus of this chapter is on skeletal muscle organization. The system
to name skeletal muscles will be explained; in some cases, the muscle is named by its
shape, and in other cases it is named by its location or attachments to the skeleton. If you
understand the meaning of the name of the muscle, often it
will help you remember its location and/or what it does.”

Identify the muscle being described (pages 328-381 in the text will help):
1. Located on the anterior side of the lower leg, lateral to the tibia - [ ]
2. Located just beneath the gastrocnemius on the dorsal side of the lower leg - [ ]
3. Beginning at the insertion on the medial, anterior side of the upper leg/knee region and ending at the
origin on the anterior superior iliac spine - [ ]
4. Located intermediate of the metacarpals - [ ]
5. Located at the distal end of the arm with origin at the elbow and insertion at the phalanges - [ ]
6. Located on the anterior side of the thoracic region spanning from the medial line to the boundary of the
deltoid and the arm pit area - [ ]
7. Spanning from the medial line on the dorsal side of the body out to the spine of the scapula - [ ]
8. Located intermediate of the ribs - [ ]
9. Encircling the oral opening - [ ]
10. Spanning the distance between the manubrium and both the occipital and inferior portion of the
temporal bone - [ ]
