Skeletal System
How many functions of the skeletal system are there?
5 (what are they)
An example of a long bone is...
(One of) Humerus, Radius, Ulna, Femur, Tibia, Fibula, Phalanges
What is the name of the muscles in the front of the upper leg called?
Quadriceps
What attaches bone to bone?
Ligaments
What is muscular hypertrophy?
Muscle hypertrophy is the increase in strength and size of skeletal muscles
How many types of bones are there?
6 (what are they?)
An example of a flat bone could include...
(one of) Sternum, Cranium, Pelvis, Ribs
Our hamstring is located.....
At the back of our upper leg
The attachment of skeletal muscles to a bone is the job of the...
Tendons
Muscles that are inactive for long periods of time are vulnerable to muscle atrophy.
What reasons would cause you to have some skeletal muscles inactive for a long duration?
Injury (muscular or skeletal), old age, burns, malnutrition, spinal cord and nerve injuries.
Classify one of the types of bones found in the human body:
Long bone - greater length than width and consist of a shaft
Short bone - have approximately equal length and width
Flat bone - thin shape/structure
Irregular - have complicated shapes
Sesamoid - Sesame seed shaped, formed in high impact areas
Sutral - Found in between bones in the cranium
What are the 3 types of bones in your wrist/hand called?
Carpals, Metacarpals, Phalanges
What are the three different types of muscle found within our body?
Smooth, Cardiac and Skeletal
List a difference that separates tendons and ligaments.
Ligaments can heal naturally, tendons cannot. Ligaments are bone to bone, tendons are bone to muscle
Atrophy is more noticeable in the muscles of the legs and arms. Why?
When injured, common recovery practice for limbs (legs and arms) is to keep them immobile. When this occurs for long periods, the muscles enter atrophy.
What are the minerals that are stored within bones?
Calcium (Ca), phosphorus (P)
What is one of the three sub-group names of the bones that protect our spine?
Cervical vertebrae, Thoracic vertebrae, Lumbar vertebrae
The type of muscle found within the inside of the small intestine is...
Smooth muscle
The ligament that has the longest minimum potential recovery time in the knee is the...
Anterior Cruciate Ligament
What is one way of maintaining muscle hypertrophy?
•Exercise on a regular basis
•Complete various exercises and training – Swimming, strength, cardio.
•Complete standard recovery techniques – Ice, stretching, hot and cold swims.
•Nutrition – Following a diet that provides adequate energy levels and promotes recovery.
Explain how the skeletal system assists with movement.
Through the attachment to muscles, when the muscles move the bones move with them
The bone on the outside position of the lower arm when standing in the correct anatomical position is the...
Radius
The name of the muscle located just under the scapula is called?
Lattisimus Dorsi (Lats)
Compare pictures of ligaments and muscles. Ligaments are commonly white, muscles are red. What does this represent?
Ligaments receive little blood flow compared to muscles. That’s why ligaments take so long to heal.
As the muscles get smaller and weaker, tasks requiring their use become harder to complete.
