Can muscle cells form cardiac and skeletal muscles?
Skeletal muscle cells are much bigger than cardiac muscle cells. Skeletal muscle fibres are up to 100 micrometers in diameter and several centimeters long while cardiac myocytes are about 15 micrometers in diameter and about 100 micrometers long.
with a lot of help you need muscles to pull on bones so that you can move
Which bones form the acetabulum?

-the cardovascular system suplies blood to all parts of the body and in that blood is nurtients that are used to build up bones and also keep them alive
What runs through the middle of the vertebrae?
A cold shiver, among other things such as the spinal chord.
What bone is unique to the axis vertebrae?
The atlas, also known as C1 sits on the axis, or C2. The dens of the axis projects through the vertebral foramen of the atlas and the vertebral facets come in contact with each other through cartilaginous discs between the two vertebrae.
What is the purpose of cartilage and where is is located?
Cartilage is a firm, elastic and flexible type of connective tissue that covers the surface of joints, allowing bones to slide over each other. It is found on the ears, nose, knees, elbows, trachea and larynx.
Is the fibula non weight bearing?
The fibula does not bear weight, but several muscles originate from it. The fibula, is the thinner bone in the lower leg, not made for weight bearing, however the tibia is made for weight bearing, which is the larger bone in the lower leg.
Does physical exercise decrease bone density?
No, it does not decrease your bone density. Rather, exercising potentially stimulates the tissues and blood vessels around your bones, prompting them to better maintain their density. While you can take actions to promote bone health, there is little you can do to directly affect increasing or decreasing your bone density intentionally.
What are the main four functions of the skeleton?
1.Supports the framework 2.Holds the body together 3.Protects internal organs 4.Helps us move
Which part of the skeleton protects the spinalcord?
A glomerulus- meaning big bony ball. It gets its name because big bony balls are often left unseen, making it a perfect layer for the vertebra. If one actually comes accross big bony balls, one is advised not to sit near magnets.

It can be be bad enough that you need surgery, or as slight as doctors dont even ask for follow ups
The smooth flexible layer of tissue covering the ends of bone is?
Hyaline cartilage is a type of tissue found at the ends of some bones.
It is an amorphous (chondroitin and glucosamine) matrix that surrounds cells that are called chondrocytes (within lacunae).
It acts as a support and as a cushion. It has little blood supply and because of that it heals poorly.
What are the differences between the fetal skull and adult skull?
the calvarium of the adult scull is fused, in the fetus the bones making up the skull are not fused (not joined together), also the're actually quiet a lot of space around the bones - called fontanelles or "soft spots" on a baby's head that you can feel on the back of the head in many babies until 6-9 months or so and on the front of many babies until 15-18 months or so.
