Transcript What are the parts and functions of the Muscular System?

TOPIC: Locomotion
Aim: Explain the structure and functions of
the 3 types of muscles.
Do Now: Explain the difference between a
ligament and a tendon.
HW: Castle Learning – Skeletal and Muscular
System
Identify
the purple
structures
in the
diagram.
Explain
their
function.
Babies are born
without the patella (knee bone)
it develops between
ages 2 and 5.
Did you know…………….
• You have over 30 facial muscles which
create looks like surprise, happiness,
sadness, and frowning.
• Eye muscles are the busiest muscles
in the body. Scientists estimate they
may move more than 100,000 times a
day!
• The largest muscle in the body is the
gluteus maximus muscle in the
buttocks.
Function of • Locomotion
the muscular • Move by contracting
system
(shortening) and
relaxing
Voluntary
muscles
• You are able to
control
–Examples: Arm & leg
muscles
Involuntary • You do not control
Muscles
consciously
–Example: Heart and stomach
muscles
MUSCLES TYPES
Smooth Muscle • Non-striated (no
stripes)
• Involuntary
• Line your
internal
organs
(digestive
system,
blood
vessels…)
Cardiac
Muscle
• ONLY in the HEART
• Involuntary
• Striated (have stripes)
• Fibers branch
Skeletal • Attached to bones
Muscle
• Voluntary
• Striated
• Work in pairs.
– One contracts while the other
relaxes
How do muscle cells get energy?
• Aerobic
respiration
(needs
oxygen)
Glucose

2. Describe where each type of muscle is
located.
3. Describe whether each type of muscle is
involuntary or involuntary.
4. Describe whether each type of muscle is
striated or non-striated.
Review: Identify the muscle being
described.
1. Involuntary
2. Striated
3. Found in the heart
4. Lines internal organs
5. Voluntary
6. Branched fibers
7. Attached to bones
