Muscles
When a muscle is said to be teres, what does it mean?
The shape of the muscle is round.
Where are Smooth or visceral muscles located?
Give one difference between long and short bone.
Long bones are longer than wide, short bones are about as wide as long.
Why are cancellous/spongey bone named that way?
named because of its holy appearance (it does not feel like a sponge, only looks like one)
Are your phalanges short of long bones?
Long bones, they are still longer than wide. The short bones of your hand are only the wrist bones.
In Muscle naming, how do you say that the muscle's direction of fibers are circular?
Orbicularis
The muscle Tissue that makes up the heart, striated and involuntary.
Cardiac Muscle
What do bone marrows do?
They store fat, produce blood cells, and play an important part in the body's immune system.
What are the two divisions of the skeletons?
Axial and Appendicular Skeleton
How many long bones does your hand have?
19 long bones
Muscle contractions need energy, so whenever energy is used in the body, some will be converted to heat that working muscles release. This action helps to keep our body temperature in normal range.
Name all the types of muscles in mammals.
1. Smooth
2. Skeletal
3. Cardiac
What are the different shapes of bones? Give an example of each.
Long (femur), short (wrist), flat (scapula), irregular (vertebrae, pelvic girdle), and sesamoid (kneecap) bones.
Explain one function of your skeletal System (explain in your own words what one of the functions actually means or give an example)
Protect our organs (ex. our skull protect the brain)
Provide framework for our movements - helps us to move with our muscles
Stores minerals via our bone marrows such as calcium and phosphate.
Produce blood cells via our bone marrow
How many bones are typically in a human body? And how many are in each division?
There are 206 bones total. 80 are part of the axial skeleton and 126 are part of the appendicular skeleton.
What are the 4 properties of muscle Tissue and what they each briefly mean.
1. Electrical excitability - muscles have neurons that passes through it, signaling it to move.
2. Extensibility - muscles can extend
3. Elasticity - muscles are elastic
4. Contractibility - muscles can contract
These muscles are cylindrical, striated and voluntary. What is it and what does it help with?
Skeletal muscle, helps with movement.
What does cavity mean in the realm of science/human body?
A hole or hallow space in our body (think about cavities in your teeth or medulary cavity)
Ligaments, Joints, or tendons. Pick one, give a definition and an example (or explain what it does)
Ligaments: Tissue that connect bones to other bones (pelvis ligaments)
Joints: where two or more bones make contact (shoulder, elbow, knee)
Tendons: attach muscles to bone (Achilles tendon)
Name different sections of your skeleton. (100 each, up to 6)
skull, spine (vertebral column), ribcage, arms and hands (upper extremities), legs and feet (lower extremities), shoulders, hips (pelvis)
What are the 5 main functions of muscles?
Produce movement, maintain posture and position, support soft tissues, protect entrances and exits, and maintain body temperature.
What are some things that affect the skeletal muscle fiber, possibly changing the diameter of the fibers?
Age, testosterone, and exercise or lack of exercise.
What type of bone shape is this? (show picture of pelvic girdle). And why?
This is an irregular bone because the shape of the bone is peculiar and cannot be defined or grouped like the other types of bones.
This(these) type(s) of bone(s) has cells which can help to make repairs if a bone is injured or broken.
Compact Bone AND Cancellous/Spongy bone.
Name as many muscles and you can (hint: use the muscle naming guide) (100 each, up to 500 pts)
Deltoids, biceps, triceps, qudriceps, gastrocnemius, gluteus maximus, gluteus minimus, etc.
