Problem 74 - Objective Biology for NEET

Question

Scapula is an example of (a) Long bone (b) Short bone (c) Flat bone (d) Irregular bone

Step-by-Step Solution

Answer

The correct answer is (c) Flat bone.

Step 1: Identify the type of bone

The scapula, commonly known as the shoulder blade, is a bone in the human body. The type of bone can be determined based on the shape and location of the bone.

Step 2: Classify the bone

From the options given, classify the scapula as a long bone, short bone, flat bone or irregular bone.

Step 3: Selection

Based on the description and shape, scapula falls under the category of flat bones.

Key Concepts

Types of Bones

Understanding the different types of bones is fundamental when studying the human skeletal system. The human body comprises several bones, each with distinct shapes and functions, classified into four main categories: long bones, short bones, flat bones, and irregular bones.

Long bones, like the femur and tibia, are crucial for large movements and are characterized by a shaft with two ends. These bones are longer than they are wide and have a tubular structure. Short bones, such as the carpals in the wrist, are cube-shaped and provide stability with limited motion.

Flat bones are thin and generally curved, providing protection to internal organs as well as a broad surface for muscle attachment. Examples include the scapula (shoulder blade), skull, and ribs. Lastly, irregular bones are those that do not fit into the previous categories due to their complex shapes. These bones, including the vertebrae and some facial bones, have varied functions depending on their locations in the body.

Skeletal System

The skeletal system is an integral part of the human body, giving it structure and support while also serving as an anchor for muscle attachment. This system is composed of bones and cartilage and performs several crucial functions such as protection of vital organs, facilitation of movement, and housing for bone marrow which is responsible for blood cell production.

When discussing the skeletal system, one must also understand the various connections between bones, known as joints, and the cartilaginous structures that provide cushioning and reduce friction. Knowing the organization of the skeletal system is vital for apprehending how specific bones function in context, like the scapula's role in shoulder movement and stability.

NEET Biology Preparation

Preparing for competitive examinations like NEET (National Eligibility cum Entrance Test) requires a deep understanding of the biology syllabus, which includes a comprehensive study of the skeletal system. Aspiring medical students should focus on concepts like types of bones and their classifications as such questions are commonly asked.

For NEET biology preparation, students should employ various study methods such as visual aids, mnemonics, and practice questions to reinforce their knowledge. Regular revision of key concepts, like the classification of the scapula as a flat bone, and attempting previous years' question papers can also significantly aid in securing a strong score in the biology section of the NEET exam.
