1. Anatomy-Muscular System
Skeletal Muscle
Naming

2. Bell Work Grab a note taker from the front table
Discuss in your groups the muscles that you know and how YOU THINK they have been named

3. Objectives Students will be able to:
Identify skeletal muscle origin & insertion
List the ways to name skeletal muscles

4. Skeletal Muscles Skeletal muscles ATTACH to bone through a tendon
Skeletal Muscles ORIGINATE on some portion of a bone and INSERT on another

5. Skeletal Muscle Attachments
Origin
Most proximal attachment
Attached to least mobile bone
Shorter tendon
Muscle fibers closer to attachment
First part of name
Insertion
Most distal attachment
Attached to most mobile bone
Longer tendon
Muscle fibers farther from attachment
Last part of name

6. Naming Skeletal Muscles
1. Action or Function
Name or part of name tells function
Flexor
Flexor Hallucis Longus
Extensor
Extensor Hallucis Longus

7. Naming Skeletal Muscles
2. Direction of fibers
Anatomical planes
External Oblique
Internal Oblique

8. Naming Skeletal Muscles
3. Location/Direction
Tibialis Anterior
Tibialis Posterior
4. Number of Tendons
Triceps Brachii
Biceps Brachii

9. Naming Skeletal Muscles
5. Shape
Geometric shapes
Deltoid
Triangular (Delta)
6. Size
Large v Small Short v Long
Gluteus Maximus
Gluteus Minimus
Pectoralis Major
Pectoralis Minor
Peroneus Longus
Peroneus Brevis

10. Naming Skeletal Muscles
7. Points of Attachments
Origin = first part of name
Insertion = last part of name
Brachioradialis
Origin-brachium
Insertion- radius

11. Not one or the other Some muscles use more than one way to name it
Tibialis Anterior
Extensor Hallicus Longus
Rectus Abdominus

12. Closure List the 7 ways muscles are named
List 3 characteristics of origins and 3 characteristics of insertions
