Skeletal System
The skeletal system provides definite shape and mechanical support to the body, and it also helps in movement and locomotion. Ask questions about the skeletal system and bones here.

Substance in the center of the bones?
The substance in the center of the bones is called Bone Marrow. There is yellow marrow and red marrow.
What are the 3 processes found on the bone?
Most vertebrae have 3 processes. The spinous process, which is the one that comes straight off of your vertebral column, can actually be felt . You can feel this one particularly well at the base of your neck (this is the 7th Cervical vertebra, also known as Vertebra prominens). The very first vertebra, C1, also known at Atlas, does not have a spinous process. Each vertebra has two transverse processes which are on either side of the spinous processes. All of these processes are important for muscle attachments for movement of the head, neck and torso.
The medial
epicondyle is a bony protrusion that can be felt on the inside part of the elbow. Part of the upper arm bone, orhumerus, it occurs at the bottom of the bone where the humerus meets theulnaat the elbow. It is larger and further back on the bone than its counterpart --- the lateral epicondyle
. The medial epicondyle
provides attachment of the ulnarcollateralligamentto the pronator teres muscle, near the back of the elbow. When theulnar nervethat runs along the back of this bone is hit, it is frequently referred to as hitting the funny bone.
Like many bones in the body, the medial
epicondyle may be rarely thought about until it is involved in an injury. Fracture of the medial
epicondyle represents the third most common elbow fracture in children, especially those 9 to 14 years old. In children and adolescents, the growth plate between the humerus and the ulna is made of cartilage cells that are softer and more susceptible to trauma than fully formed, mature bone. It is possible in extreme injuries for the growth plate to tear from the connection with the bone, resulting in an convulsion fracture.

What is the function of the pelvic?
In all animals with legs, its use to connect the back legs to the spine. In female mammals, its wider so that offspring can have room to develop. In humans, its unique shape is what allows us to walk upright.
We know that,
g1=G.m/R2
so, g is inversely proportional to R2.
And, if Radius of the earth(R) is doubled, the distance between the object and the centre of the earth will become 2R.
Now, g=G.m/(2R)2
=> g2=G.m/4R 2
=> g2=1/4(G.m/R2)
Since, G.m/R2 =g1
=> g2=1/4 g1
Here, g1=9.8 m/s2
So, g2=9.8/4 m/s2
=2.45 m/s2
Where in your body would you find the cruciate ligament?
The cruciate ligament is found in your knee.
The joint between the shoulder and upper arm is an example of which kind of joint?
Ball-and-Socket.

What does abnormal MRI brain demonstrating heterogeneous bone signal mean?
Many things, most common is anemia. Differntial is multiple myeloma, mets, leukemia, and myelofibrosis. Findings have to be correlated with patient history and labs.
What protects your inner organ?
the bones gives support and protection
Actually it's muscle, Muscle provides physical support by counter balancing the body on the bones by flexon and extension. It also protects the other organs from damage by it's density and tone adding resistance to penetration of the more delicate thoracic cavity.
When newborns are grown into adults do they grow new bones?
basicly yes!
ANS2:As the skeleton matures the growth plates at the ends of long bones fuse and sessamoidal bones, such as the patella, form. On the whole, more bones fuse than do new bones form so an adult skeleton has fewer bones than an infant's skeleton.the medial malleolus
How does the malleus in the ear work?
The malleus, incus, and stapes are a chain of small bones in the middle ear. Sound waves hit the ear drum and together with the other bones it tends to transmit the vibrations from the ear drum to the cochlea to the brain so as to unable one to hear.
Does the frontal bone protect the anterior portion of the brain?
Yes, the frontal bone protects the anterior portion of the brain. It forms the forehead and the upper part of the eye sockets, serving as a barrier against physical trauma. By encasing the frontal lobes of the brain, it helps safeguard these vital areas responsible for higher cognitive functions, decision-making, and emotional regulation.
