Long bones function in
- support
- support, erythrocyte and leucocyte
- support and erythrocyte synthesis
- erythrocyte formation.
The Correct Option is B
Approach Solution - 1
Approach Solution -2
Ans: Long bones are the ones that are longer than how wide they are. They have a shaft and two ends (epiphyses). They have many essential functions in the body and are a major part of the human skeleton system:
- Support: A structural support is provided by the long bone, to the entire body. They act as the pillar and form the framework.
- Movement: The skeleton muscles are attached to these long bones and thus help in the movement and during the physical activities.
- Protection: Long bones like femur, humerus help in protecting the delicate structures.
- Blood cell production: The long bones have the bone marrow where the production of cells takes place. This process of production is known as hematopoiesis.
- Mineral storage: These long bones act as a reservoir for minerals. They are released into the bloodstream when they are needed.
- Some of the examples of long bones are femur, tibia, fibula, radius etc.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.

Locomotion and Movement
Locomotion
The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.
Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement
Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
