Transcript Notes: Body Movements Slide 6.32

Do Now: 3 Types of Muscle Tissue
 Directions:
Review your
notebook and
tissue foldable.
Fill-in the
blanks.
Turn to this picture in your notebook
of MUSCLE MOVEMENT!
Standard AP 2.9
Identify major skeletal muscles on a diagram
of the human body’s and describe the
movements associated with each of them.
Directions:
Scientists – pick up papers
from the lab
materials table for your lab team.
Glue in the pictures as you take
notes in your science notebook.
Names of Major Muscles
Highlight the
names of
muscles you
learned last year.
• Glue this
picture on the
next blank
page of your
notebook.
Naming of Skeletal Muscles
 We have over 650 skeletal muscles.
 How are they named?
 Where do the names come from?

Slide
6.36a
Naming of Skeletal Muscles
 Direction of muscle fibers
 Example: rectus (straight)
 Relative size of the muscle
 Example: maximus (largest)

Slide
6.36a
Naming of Skeletal Muscles
 Location of the muscle
Example: many muscles are named
for bones (e.g., temporalis)
 Number of origins
Example: triceps (three heads)

Slide
6.36b
Naming of Skeletal Muscles
 Location of the muscles origin and
insertion
 Example: sterno (on the sternum)
 Shape of the muscle
 Example: deltoid (triangular)
 Action of the muscle
 Example: flexor and extensor (flexes or
extends a bone)

Notes: Body Movements
Review this diagram with your lab group!
Remember…today’s exit slip will require you
to DRAW limbs (arms and legs) in specific
muscle movements!
Notes: Body Movements
 Movement is
achieved by
muscle moving
to an attached
bone.

Slide
6.30a
Notes: Body Movements
 Muscles are
attached to at
least two points
 Origin – (start)
attachment to a
fixed bone
 Insertion – (end)
attachment to a
moveable bone

Slide
6.30b
Notes: Body Movements
 Flexion
 Decreases angle of joint, brings two bones
closer together
 Bending elbow
 Extension
 Opposite of flexion, increase angle of a joint,
two bones moving further apart
 Straightening elbow

Slide 6.32
Notes: Body Movements
 Rotation
 Moving a bone around it’s x or y-axis
 Turning head
 Abduction (AB- duction)
 Moving a bone AWAY from midline
 Adduction (think…ADD to body)
 Moving a bone CLOSER to midline

Show me FLEXION at the shoulder joint
Show me EXTENSION at the knee joint
Show me ROTATION at the cervical spine
Show me ABDUCTION at the hip joint
Show me ADDUCTION at the hip joint
Checking for Understanding
Write in your notebook!
1. What is the difference between the origin of
a muscle and the insertion point?
Write in COMPLETE SENTENCES in your
notebook. Be prepared to share out!
Reading
Directions: On your own…Read and
annotate the text (double sided). See the
blue annotation marks examples in your
yellow folder.
Group Work
Directions: Work with your lab group to
complete the classwork packet. This packet
also includes information on the anatomy of
skeletal muscle.
See page 195 – 203 in your textbook
and use your ipad. You will have 20 minutes
(double sided). Be sure to check your yellow
folder for ANSWER KEYS!
Remember…Be prepared to LABEL
major skeletal muscles on a diagram!
