Bending of ankle joint is brought about by

Options

A. Biceps
B. Triceps
C. Trapezius
D. Gastronemius

Answer

To answer the question "Bending of ankle joint is brought about by," we need to identify the muscle responsible for this action. Here’s a step-by-step solution:

### Step 1: Understand the Ankle Joint Movement
The ankle joint allows for two primary movements: dorsiflexion (bending the foot upwards) and plantarflexion (bending the foot downwards).

**Hint:** Think about the directions in which the foot can move at the ankle joint.

### Step 2: Identify the Relevant Muscles
The main muscles involved in the movement of the ankle joint include:
- Gastrocnemius
- Soleus
- Tibialis anterior
- Peroneus muscles

**Hint:** Consider which muscles are located in the calf region and their roles in moving the foot.

### Step 3: Focus on the Gastrocnemius Muscle
The gastrocnemius muscle is a major muscle of the calf that plays a crucial role in plantarflexion of the ankle joint. It is responsible for bending the ankle joint downwards.

**Hint:** Recall that the gastrocnemius is often associated with movements like standing on tiptoes or pushing off the ground.

### Step 4: Eliminate Incorrect Options
- The soleus muscle, while also involved in standing and stabilizing, primarily assists the gastrocnemius.
- Biceps and triceps are muscles of the upper limb and do not affect the ankle joint.

**Hint:** Think about the location of each muscle and whether they are part of the lower limb.

### Step 5: Conclude with the Correct Answer
Based on the analysis, the muscle responsible for bending the ankle joint is the gastrocnemius.

**Final Answer:** The bending of the ankle joint is brought about by the gastrocnemius muscle.
