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.
14,490 Questions
What is a major function of the skeletal system?
Support, protection, movement, shape, and red blood cells
What system consists of bones and the tissues connecting them?
It is made of body cells just like the rest of your body cells-tissues-organs-systoms-your body
Which bone articulate with metatarsal bones?
Distal to the metatarsals are the phalanges. The great toe (hallux) has two phalanges where as all of the other toes have three each. The proximal phalanges attach the the metatarsals via the metatarsal phalangeal joints. Proximal to the metatarsals are the tarsals. The first, second, and third cuneiforms articulate with the first, second and third metatarsals. The fourth metatarsal articulates with the cuboid and the head of the fifth metatarsal is its own projection that can be felt on the lateral foot.
Your hip and back bone take the same interesting role in your body. The hip and back bones make you run, walk, sit, stand, bend, and anything else involving moving. If you did not have those bones in your hip and your back, you'd be like a giant spaghetti! the hip bone protects the organs in your ribs.
There are joints in the ribs. There are the joints of the sternum, the joints of ribs, and the joints of costal cartilages.
What if your humerus is an example of what type of bone?
The humerus bone is the long bone in your upper arm. In simple terms, it goes from your shoulder down to your elbow. But heres the names for all the bones is conects to starting from the shoulder area:
The humerus bone connects to two parts of the scapula bone (shoulder blade) which are the acromoin and the coracoid process. Near the elbow, the humerus bone connects with the olecranon process and the head of the radius.

Is the ulna proximal or distal to the radius in directional position?
The humerus is proximal to the radius. The humerus is the upper arm bone, and the radius is the main bone of the forearm.
What are the 2 long bones with large joints?
Although your question is not precise, but I'll answer it
1- The knee joint which is a biaxial synovial joint of the condyloid variant
it is formed by the 2 long bones femur & tibia
2- The elbow joint which is a uniaxial synovial joint ( hinge variant )
it is formed by three long bones humerus, radius, and ulna
Short term effects of exercise?
However different types of exercise will have different effects upon the muscles exercised. For example high intensity low duration exercise will produce strength, size and power gains while low intensity long duration exercise will produce endurance type benefits.Tone; Refers to the state of readiness of a muscle. This is the state that a muscle is in when it is relaxed and how able it is to respond to its task. An unused, untrained muscle will have poor tone and will respond slowly and with greater difficulty to a task than a trained muscle.Posture; Refers to the way in which we hold our bodies when sitting, walking or running. Regular exercise performed correctly will encourage good posture which enables muscles to work efficiently and will help to prevent injuries.Hypertrophy; Is when a cell, in this case a muscle cell, increases in size through growth. Extreme hypertrophy may result in the cells splitting to create new ones.Atrophy; Is when a muscle shrinks due to injury or lack of use. so that is the short term effect of exercise on the muscular system.
Which protect internal organs?
The important functions of the muscular system in the human body are described as follows:
1. MovementsSkeletal muscles help in the voluntary movements of each and every human body part. Active contraction of these muscles occurs at the expense of energy, which creates a force that moves the body parts.
2. Posture and stabilityHuman skeleton is composed of bones and the joints that are formed between them. Skeletal muscles play a major role in stabilizing human skeleton. They also help in maintaining proper posture of human body.
3. Heat productionAs already stated, active contraction of muscles requires energy. Hence, muscles use a great amount of body's total energy. Due to this the body's metabolic rate is increased, producing a large amount of heat in the body.
4. CirculationCardiac muscles are responsible for forcing the blood out of the heart and pumping it throughout the human body.
How many bones are there in new born baby and in an adult?
A baby has about 300 bones or in other words 270 bones in their body. An adult has 206 bones in their body. A baby has more bones in their body because as they grow up they need these bones to fuse together causing them to be bigger and most likely stronger normally That's why a baby has more bone than an adult does.
How mamy bones are in the human body?
There are 30 bones in the skull.
Although it might look like one shaped hollow bone, the skull is actually made up of 30 different separate bones.Some of these bones protect your brain, while others make up the structure of your face. If you touch beneath your eyes, you can feel the ridge of the bone that forms the hole where youe eye sits.
therer are only 22 bones in the skull 8 cranial and 14 facial bones.
what do you mean by that? Are you too skinny to have breasts? Or are you not growing breasts for some medical reason or what?
What bones do not have red bone marrow?
Bone marrow is the tissue that is in the center of large bones.
Answer given by: Nora
Why is the skeleton system necessary for survival?
The cardiovascular system is responsible for transporting the necessary nutrients to the individual bones for healthy growth. The bone marrow produces erythrocytes (red blood cells) that deposits in the veins to reach the rest of the body.
What bones of the pelvis do we sit on?
The bone that you sit on is also known as the sits bones. The scientific name is the ischium which is a large swelling posteriorly on the superior ramus of the ischium.
Why can it take months for a bone to heal?
Because a bone in your body is very rough and hard, the bone's healing time depends on the size of the damage, if the bone is completely snapped then it will take longer then a cut because it is bigger damage whereas a cut can seal itself.
The skin as such is made up out of organic soft material where cells can multiply very fast given the right conditions.
Our bone structure is made up out of specialized cells that absorbs a lot of calcium (and other components) that hardens them over time.
A bone heals quite quick though as in having or getting the cells needed in order to "glue" it back together again. This happens much at the same rate as skin cells would heal up.
It is the process of hardening and strengthening this freshly formed new material that is responsible for the long time it takes.
A broken bone will rarely break at the same place again after it is healed though. The fracture actually make the bone structure stronger where it happened due to "scar tissue" or extra bone material being deposited in and around the fracture.
Skin with scar tissue does not experience this effect and will be weaker for a really long time afterwards, often through life, although not much weaker.
