In what type of fracture do we consider the bone to be shattered?
Transverse.
Spiral.
Comminuted.
Greenstick.
The Correct Answer is C
Choice A is incorrect because transverse fractures are the type of fractures where the bone has a horizontal fracture line.
They are usually caused by a strong force applied at a right angle to the bone shaft.
Choice B is incorrect because spiral fractures are the type of fractures where the bone has an angled fracture line that curves around the bone shaft.
They are usually caused by a twisting force applied to the bone.
Choice D is incorrect because greenstick fractures are the type of fractures where the bone is bent and partially broken on one side.
They are usually seen in children whose bones are softer and more flexible than adults.

Correct Answer is ["Mastoid process"]
Explanation
The mastoid process is a bony prominence located on the temporal bone of the skull, behind the ear.
It serves as an attachment site for several muscles, including the sternocleidomastoid and the splenius capitis.
The mastoid process also contains small air cells that are connected to the middle ear, which play a role in regulating the pressure within the ear.
In addition, the mastoid process is located in close proximity to several important structures, including the facial nerve, the internal jugular vein, and the sigmoid sinus.
Injuries to the mastoid process can occur as a result of trauma, infection, or tumors, and can cause pain, swelling, and other symptoms.
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.
