Humerus is different from femur by presence of :-

Options

A. Spines
B. Deltoid Ridge
C. Glenoid cavity
D. Carpals

Answer

To solve the question of how the humerus differs from the femur, we can follow these steps:

### Step 1: Understand the Bones
- The humerus is the long bone in the upper arm, while the femur is the long bone in the thigh. Both bones are part of the skeletal system but serve different functions and are located in different parts of the body.

### Step 2: Identify Key Features
- We need to identify specific features that differentiate the humerus from the femur. The options provided are:
1. Spines
2. Deltoid Ridge
3. Glenoid Cavity
4. Carpals

### Step 3: Analyze Each Option
- **Spines**: Both bones do not have significant spines that differentiate them.
- **Deltoid Ridge**: The humerus has a deltoid ridge, which is an important site for muscle attachment, specifically for the deltoid muscle.
- **Glenoid Cavity**: This is part of the scapula and is not a feature of the humerus itself.
- **Carpals**: These are wrist bones and are not related to the structure of the humerus or femur.

### Step 4: Conclusion
- The presence of the **Deltoid Ridge** in the humerus is what makes it different from the femur. The deltoid ridge serves as an attachment point for muscles, which is not found in the femur.

### Final Answer
- The humerus is different from the femur by the presence of the **Deltoid Ridge**.
