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 ["Scaphoid bone"]
Explanation
The carpal bones, also known as the wrist bones, are a group of eight small bones located in the wrist joint.
They are arranged in two rows of four bones each, with the rows separated by a space known as the carpal tunnel.
The carpal bones are held together by ligaments, and their shape and arrangement allow for a wide range of wrist movements.
The names of the carpal bones, from the proximal row to the distal row, are the scaphoid, lunate, triquetrum, and pisiform, and the trapezium, trapezoid, capitate, and hamate.
Each bone has a unique shape and surface features that allow it to articulate with adjacent bones, forming a complex network of joints that are important for wrist and hand movements.
The carpal bones are important because they provide stability to the wrist joint, allowing for precise movements of the hand and fingers.
They also help to transfer forces from the hand to the forearm, and vice versa.
Injuries to the carpal bones can result in wrist pain, instability, and decreased function of the hand and fingers.
Additionally, the arrangement of the carpal bones can affect the function of the median nerve, which runs through the carpal tunnel.
Compression or irritation of this nerve can result in carpal tunnel syndrome, a condition characterized by pain, numbness, and tingling in the hand and fingers.
Correct Answer is A
Explanation
The skeletal system has five main functions: support, movement, protection, mineral and fat storage, and blood cell formation.
All of the other choices are primary functions of the skeletal system.
Choice B is incorrect because storing inorganic salts is one of the functions of the skeletal system.
The bone tissue acts as a reservoir for minerals like calcium and phosphorus.
Choice C is incorrect because attachment sites for muscles is one of the functions of the skeletal system.
Bones facilitate movement by serving as points of attachment for muscles.
Choice D is incorrect because support and protection is one of the functions of the skeletal system.
Bones provide a scaffold that supports the body and protects the internal organs.
