Q. 32 - Biology

Question

What movements occur at the hip joint and knees as you bend down to touch your toes? 

Step-by-Step Solution

Answer

With the knees extended, the hip joint is flexed. 

Step 1 : Introduction

The synovial joints' wide range of motion allows for a variety of movements. Synovial joint movement can be classified into four types: gliding, angular, rotational, and special movement. Gliding occurs when relatively flat bone surfaces pass each other. 

Step : 2 Movement causes the knee to bend.

• Regular knee flexion involves sliding and rolling between the tibia and femoral condyle surfaces that come into contact. 
• The patella shifts from the superior (shallower) to the inferior (deeper) section of the trochlear groove during knee flexion. 

Step : 3 Hip joint

• The hip joint, which connects the axial skeleton with the lower extremity, is where the pelvis and femur articulate. 
• A ball-and-socket joint, the hip joint offers the stability required to support body weight while allowing for movement.
