The Musculoskeletal System• Functions:
– Locomotion and protection
– blood production in the bone marrow
– heat generation,
– maintenance of posture and
– storage of minerals

The Muscles
Three types of muscles exist in our body
• Voluntary skeletal muscle
• Involuntary cardiac muscle
• Involuntary visceral smooth muscle
![Page 5: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/5.jpg)

The Muscles
Muscles are composed of
muscle fibers having numerous nuclei and striations

Properties of Muscles
• Electrical excitability
– Ability to contract to certain stimuli
• Contractility
– Ability to contract forcefully when stimulated
• Extensibility
– Ability to stretch without being damaged
• Elasticity
– Ability to return to its original length and shape
![Page 9: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/9.jpg)

Muscle Physiology
• Muscle fibers are enclosed sheaths- perimysium, epimysium
and endomysium
• Each muscle cell has actin and myosin filaments arranged in a
sarcomere
• This sarcomere is the basic structural unit of the muscle
![Page 10: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/10.jpg)
diannemaydee (tm)
Muscle Physiology
• Muscle contraction occurs as actin and myosin slide past one
another causing the sarcomeres to shorten
• Calcium ion is released by the muscle endoplasmic reticulum
to initiate contraction
• ATP is used both for muscle contraction and muscle relaxation
![Page 11: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/11.jpg)

Muscle Physiology
Muscle contraction can be of two types
• 1. ISOMETRIC- iso= same, metric=distance: The length of the
muscle does not change, but the tension increases
• 2. ISOTONIC- iso=same, tonus=tone: The amount of muscle
tension is constant but the length of the muscle varies
![Page 13: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/13.jpg)
diannemaydee (tm)
Muscle Physiology
• Muscle tone= refers to the constant tension produced by
muscles of the body for long periods of time
FAST-twitch muscles= contract quickly and fatigue quickly
SLOW-twitch muscles=contract slowly and are more resistant to
fatigue
![Page 14: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/14.jpg)

Muscle Physiology
• Smooth Muscle= is not striated, contracts more slowly, is
autorhythmic and under involuntary control
• Cardiac muscle- is striated, is autorhythmic, and under
involuntary control
![Page 15: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/15.jpg)

Classification of Bones
• Long bones- - These bones have a shaft and ends. Ex: tibia,
humerus, femur
• Short bones- Small and cubical shaped- Ex: carpals and tarsals
• Irregular bones- vertebrae, mandible
• Sesamoid bones- bones embedded in the tendons. Ex:patella
• Flat bones- with spongy bones inside. Ex: scapulae, ribs,
clavicle
![Page 28: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/28.jpg)

Structure of the bone
• Long bones have a diaphysis ( shaft) and epiphysis (ends)
� Bones consist of layers of calcified matrix occupied by bone
cells.
� The outer layer of bone is composed of dense compact bone
(cortical bone)
� The inner layer is composed of spongy cancellous bones

Bone Structure
• Blood supply of bones reaches by way of arterioles in the haversian canal, through the vessels in the Volkmann's canal
• Bone formation can be from the cartilage and from the membrane
![Page 31: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/31.jpg)

Bone Structure
• OSTEOBLAST- bone cell responsible for bone formation and calcification
• OSTEOCLAST- bone cell responsible for bone resorption and destruction
![Page 32: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/32.jpg)

Bone Ossification
• Ossification is the formation of bone by the osteoblasts. This
involves the mineralization of bones from a cartilage
(endochondral) and from a membrane (membranous).

Bone Remodeling
• Bone remodeling involves the removal of old bones by cells
called osteoclasts and deposition of new bones by the
osteoblasts.
• Bone is the major storage of calcium
• If calcium levels in the blood falls, it is removed from the bone
![Page 36: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/36.jpg)
diannemaydee (tm)
Bone repair
• When a bone is broken, blood vessels are also damaged�clot
• 2-3 days after injury, blood vessels and cells invade the blood clot� callus formation
• Osteoblasts enter the callus and begin to form a spongy bone
• Immobilization of the bone is required because the delicate new matrix of bone is easily damaged by excessive movement
![Page 37: MUSKULOSKELETAL supplemental slides](https://reader034.fdocuments.net/reader034/viewer/2022052410/553e3a5a55034695438b491b/html5/thumbnails/37.jpg)
