Muscle Kinesiology
Anatomy & Physiology
Who came up
with those
LONG names?
Many of the names
come from Latin
and the regional
skeletal bones
How many skeletal
muscles can you
name?
Muscle Movement
Movement produced by contraction
and pulling on attached bone
Point of attachment of tendons to
bones is called
ORIGIN: attachment to
INSERTION: attachment to
Group Action: muscles working in
groups to produce body movement
Prime Movers: (agonist) Muscles
primarily involved in
Antagonists: Muscles that
Synergist: (helper) muscle that
Primary Antagonistic Actions of
Muscular system (examples of)
1.Flexion/Extension:
2.Abduction/Adduction:
3.Elevation/Depression:
various parts of
Cont.
4.Pronation/Supination: flexor and
extenson muscles in
5.Dorsiflexion/Plantar flexion:
tibialis anterior and soleus=
6.Inversion/Eversion:tibialis anterior
and peroneus longus=
Seven ways we name muscles
CHARACTERISTIC
EXAMPLES
1.Direction of fascicles
relative to midline
rectus =
transverse =
perpendicular
oblique =
2.Location (i.e. the
bone or body part
that a muscle
covers)
3.Relative Size
frontal bone
tibia
maximus =
longus =
brevis =
EXAMPLES IN HUMANS
Muscle naming cont’
4.Number of Origins
(Heads)
biceps = 2 origins
triceps = 3 origins
5. Shape
deltoid =
trapezius =
serratus =
orbicularis =
origin =
insertion =
Deltoid
Trapezius
Serratus anterior
Orbicularis oris
Sternocleidomastoid
flexion
extension
adduction
Flexor carpi radialis
Extensor digitorum
Adductor longus
6. Location of Origin
and/or Insertion
7. Action of Muscle
Kinesiology Homework
Using your Textbook, please label the
muscles in your muscle packet
L3:Create an outdoor (or indoor)
exercise/action and describe which
muscles are involved. For example:
Kicking a soccer ball would involve 4
PM muscles—Which 4??
Create and Chart 3 separate
activities
