What connects bone to bone?
None of these.
Ligaments.
Tendons.
Syndesmosis.
The Correct Answer is B
A ligament is a type of fibrous connective tissue that connects bone to bone. It usually serves to hold structures together and keep them stable.
For example, the anterior cruciate ligament (ACL) connects the femur and the tibia in the knee joint.
Choice A is incorrect because none of these is not a valid answer.
Choice C is incorrect because tendons are fibrous connective tissues that connect muscle to bone.
For example, the Achilles tendon connects the gastrocnemius muscle to the calcaneus bone in the ankle.
Choice D is incorrect because syndesmosis is a type of fibrous joint that connects two bones by a ligament or an interosseous membrane.
For example, the distal tibiofibular joint is a syndesmosis joint.

Correct Answer is ["Clavicular notch"]
Explanation
The clavicular notch, also known as the sternal notch, is a shallow, V-shaped depression located at the superior aspect of the sternum, which is the long, flat bone in the center of the chest.
The clavicular notch serves as the articulation site for the medial end of the clavicle bone, forming the sternoclavicular joint.
This joint allows for movements of the clavicle and shoulder girdle, including elevation and depression of the shoulder and rotation of the scapula
.
Correct Answer is ["Flexion of the hip joint"]
Explanation
Hip flexion refers to the movement of the thigh bone (femur) towards the front of the body, bringing the knee closer to the chest.
This movement is achieved by the contraction of muscles in the front of the hip, including the iliopsoas and rectus femoris muscles.
The joint involved in hip flexion is the hip joint, which is a ball-and-socket joint formed by the articulation between the head of the femur and the acetabulum of the pelvis.
This joint allows for a range of movements, including:
1. Hip extension: This refers to the movement of the thigh bone backwards, away from the front of the body, which is achieved by the contraction of muscles in the back of the hip, including the gluteus maximus and hamstrings.
2. Hip abduction: This refers to the movement of the thigh bone away from the midline of the body, towards the side, which is achieved by the contraction of muscles on the outside of the hip, including the gluteus medius and tensor fasciae latae.
3. Hip adduction: This refers to the movement of the thigh bone towards the midline of the body, which is achieved by the contraction of muscles on the inside of the hip, including the adductor muscles.
4. Hip external rotation: This refers to the movement of the thigh bone away from the midline of the body and outwards, which is achieved by the contraction of muscles on the back of the hip, including the piriformis and gemellus muscles.
5. Hip internal rotation: This refers to the movement of the thigh bone towards the midline of the body and inwards, which is achieved by the contraction of muscles on the inside of the hip, including the gluteus minimus and tensor fasciae latae.
All of these movements of the hip joint are important for walking, running, and other activities that require the use of the lower limbs.
Additionally, a lack of hip flexibility or strength can lead to compensatory movements in other parts of the body, which can result in pain or injury over time.
