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.

What is the Trabeculae carneaes function?
provides turbulence flow of blood and also serves a similar function as the papillary muscles (pills on the chordae tendineae which are attached to the atrioventricular vlaves, preventing them from prolapsing into the atria)
How long does it take torn ligaments in a foot to heal?
It will depend on how badly torn the ligament is.
- A grade 1 tear, which is only slight tearing of a few collagen fibers in the ligament that results in a little pain and probably no bruising or inflammation, will heal in 1-3 weeks.
- A grade 2 tear, which is moderate tearing of many collagen fibers in the ligament that results in lots of pain and probably will also cause bruising and/or inflammation, will heal in 2-6 weeks.
- A grade 3 tear, which is the complete tearing of a ligament, will not ever heal without surgery.
What happens when the diaphragm moves downward and the rib cage moves up and out?
The opposite. When you exhale, the diaphragm moves upward to push the air out of the lungs.
Can you live without some bones?
Probably not. The organs and tissues of the body require bones to anchor them, and the bone marrow is the source of most red blood cells. The vertebrae protect the spinal column which operates the nervous system, and the skull protects the brain.
You need either your skeleton or some really advanced structures to replace it.
Does the appendicular skeleton support your body?
They are the arms and legs and are used for external mobility.
What is the part of long bone that form a joint with another bone?
The epiphysis is the end of the long bone whereas the diaphysis is the shaft or body.
How many total bones for baby?
There are about 320 bones in a baby's body, but as they grow, some fuse together. An adult body has 206 bones.
Do bones act as passively operrate levers to move the body?
No. Bones help keep our body the right shape, and are moved by muscles, but muscles use the protein from our food as the energy to move them.
How many bones form the orbit?
yo mama In anatomy, the orbit is the cavity or socket of the skull in which the eye and its appendages are situated. "Orbit" can refer to the bony socket,[1] or it can also be used to imply the contents.[2] In the adult human, the volume of the orbit is 30 ml, of which the eye occupies 6.5 ml
Can germs travel through your spine?
This would be a rare situation, but if germs get into the cerebro-spinal fluid, then they would be able to travel through the spine.
What are the four main structures in the skull?
Neuroanatomists usually consider the brain to consist of six main regions: the telencephalon (cerebral hemispheres), diencephalon (thalamus and hypothalamus), mesencephalon (midbrain), cerebellum, pons, and medulla oblongata.
What is the function of the bone in the middle ear?
These are responsible for transferring and amplifying the vibrations from outer ear to inner ear
What is the function or job of the skeletal system?
There are 5 main functions; SHAPE, SUPPORT, MOVEMENT, PROTECTION and BLOOD PRODUCTION
The skeleton in vertebrate animals has many functions: provides support, protection, locomotion, stores minerals, and produces blood.
Without the skeleton, our body has no structure. We would simply be masses of skin, organs, blood, and useless muscles (they have no bones to move) in a heap on the ground.
Shape and Support
Movement
Production
Storage
Protection
The main function of skeleton is to support the muscles of the body through the tendons which serve as a connection between muscles and bones. It gives shape to our body.The bones contain nearly 85% of calcium.It plays a considerable role in immunity by containing the bone marrow which produces the WBC
The functions of a skeleton are
Movment-the movement of bones
storage-bones store marrow
structure-the bones fit together to make a skeleton and without the skeleton we wouldn't have structure and would be a ball.
protection-the bones protect the organs inside them eg.The ribs protect the heart, intestines and liver.
The functions of the skeleton are, Movement, Protection for your vital organs, Support and to make blood.
Support, movement, protection, storage of minerals, and produces blood.
Support, Protection, Movement, Mineral Storage, and Hematopoiesis
It's actually homeostasis. What the flip is Hematopoiesis?! And actually the functions are:
1.Support the body
2.Provide Proection
3.Enable Movement
4.Store Minerals
And the one you got wrong. . .
5. Make red and white blood cells
If you don't know the answer, then don't even try to answer the question! the function of the skeleton is to support the body and the weigh
there are a few functions...
1) protection of organs eg. the ribs protect the heart
2) movement it provides joints e.g the ball and socket in the shoulder
3) Storage - storing vitamins and calcium 4) support to skin and other overlying organs
Protection, support, movement and mineral storage. so our body can stand up straight. so our body can stand up straight.
What bone connects shoulder to elbow?
the shoulder bone is called the shoulder blade or scapula
There are three bones that make up the shoulder unit: the clavicle (or collarbone), which is the connection between the arm and the trunk, the scapula (or shoulderblade), which connects to the clavicle at the acromion process and contains the glenoid, which together with the humerus, forms the glenohumeral joint, or what is better known as the "shoulder joint." These three are functionally inseparable, however.
What is the stimulus for the knee jerk reflex?
Striking the patellar tendon with a tendon hammer just below the patella stretches the muscle spindle in the quadriceps femoris muscle. This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L4 in the spinal cord, completely independent of higher centres. From there, an alpha-motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction. This contraction, coordinated with the relaxation of the antagonistic flexor hamstring muscle causes the leg to kick. This reflex is a reflex of proprioception which helps maintain posture and balance, allowing to keep one's balance with little effort or conscious thought.
The patellar reflex is a clinical and classic example of the monosynaptic reflex arc. There is no interneuron in the pathway leading to contraction of the quadriceps muscle. Instead the bipolar sensory neuron synapses directly on a motor neuron in the spinal cord. However, there is an inhibitory interneuron used to relax the antagonistic hamstring muscle.
How soon can you fly long haul after an op for a broken femur?
I am having a abdominal hysterectomy on the 22 August and am due to fly on the 7 September, will I be okay to fly if I take all the necessary precautions?
This will depend on type of hysterectomy you are having. Laproscopic recovery times are much quicker than abdominal BUT you should ask your surgeon and doctor as you may need a certificate of fitness to travel for the airline. GOOD LUCK
How does the muscular system interact?
A muscle is made up of hundreds of thousands of cells, specially conditioned to be able to tighten in on themselves, and relax, that allows free control of muscles, as bones, pivoting on the joints, are moved by the contractions.
What does abnormal bone marrow signal mean?
When an mri shows abnormal bone marrow signals in the hip, there could be a number of causes. The causes vary based on whether the abnormality is in the red or yellow marrow. You will need to consult a physician to discuss the possible reasons for the abnormality.
What is the longest and smalest bone of the body?
The femur bone is the largest bone. The average length of a femur in an adult male is 50.5 centimeters. The smallest bone is called the stirrup bone, and it is located in the ear. It is only 2-3 millimeters long. It is shaped like a "U" and is the innermost bone that receives sound vibrations. They they transmit these vibrations to the cochlea and then into the brain to be interpreted by the brain.
