Joints are the points where the bones of the skeleton join together. An articulation is another name for a joint. The majority of joints are built in such a manner that they can move about. Not all joints, however, allow for mobility. The amount and direction of the motions allowed by joints that do enable movement varies. Joints are divided into structural and functional categories. The way the bones link to each other determines the structural categorization of joints. The type of the mobility that joints enable determines their functional categorization. Because function is mostly determined by structure, there is a lot of overlap between the two sorts of categorization.

  1. Which of the following is not a joint function?

a) Articulations 

b) Allows bone growth 

c) Enables mobility 

d) Supports body 

Answer: d 

Explanation: Joints are the spaces between bones. Their roles include articulating bones with one another, allowing bones to develop, and allowing movement and mobility. Bones sustain the body, while joints do not.

  1. Which of these is the location where bones and cartilage meet?

a) Tendons 

b) Ligaments 

c) Joints 

d) Fascia 

Answer: c 

Explanation: Between bones and between bones and cartilages, there are joints. As a result, they are the contact places for bones and cartilage. Tendons connect bone to muscle, whereas ligaments connect bone to bone.

  1. What do joints do when they move?

a) Effort 

b) Lever 

c) Fulcrum 

d) Load 

Answer: c 

Explanation: Muscles are the primary source of movement. Muscles contract when they receive a signal from the nervous system. This force is transmitted via joints, which serve as fulcrums for movement.

  1. Which of the following is not a joint classification?

a) Connective 

b) Fibrous 

c) Cartilaginous 

d) Synovial 

Answer: a 

Explanation: Joints are the sites where bones link to one other and to cartilages. Fibrous joints, cartilaginous joints, and synovial joints are the three kinds. Tissue that is classified as connective is called connective tissue.

  1. Which of these joints does not move at all?

a) Fibrous 

b) Synovial 

c) Pivot 

d) Cartilaginous 

Answer: b 

Explanation: Fibrous joints, cartilaginous joints and synovial joints are the three kinds of joints that exist. Due to the existence of strong fibrous connective tissues, fibrous joints do not move.

  1. Which of these doesn’t move at all?

a) Joint between atlas and axis 

b) Knee joint 

c) Skull bones 

d) Joints between carpals 

Answer: c 

Explanation: There is no mobility in the joints of the skull bones. Fibrous joints are what they are. A hinge joint is the knee joint. The pivot joint between the atlas and the axis is a gliding joint, while the gliding joint between the carpals is a pivot joint.

  1. Which of the following connects the skull bones to create the cranium?

a) Dense fibrous connective tissues 

b) Loose fibrous connective tissues 

c) Specialized connective tissue 

d) Dense irregular connective tissue 

Answer: a 

Explanation: The joints between the bones of the cranium are fibrous joints. They don’t move at all. To create the cranium, the skull bones are joined end-to-end with the aid of strong fibrous connective fibres.

  1. What is the name of the immovable juncture between two bones?

a) Socket 

b) Saddle 

c) Hinge 

d) Suture 

Answer: d 

Explanation: The existence of fibrous joints causes a suture, which is an immovable junction between two bones. Fibrous joints, such as those found in the skull bones, prevent the bones from moving.

  1. What is the sort of joint that connects the neighbouring vertebrae?

a) Pivot joint 

b) Fibrous joint 

c) Cartilaginous joint 

d) Gliding joint 

Answer: c 

Explanation: Between neighbouring vertebrae, there is a cartilaginous junction. The presence of cartilage distinguishes these joints. Cartilaginous joints allow the body component to move in a restricted range of motion.

  1. Bones are connected together at synovial joints by cartilages. Is this true or false?

a) True 

b) False 

Answer: b 

Explanation: Fibrous joints, cartilaginous joints, and synovial joints are the three kinds of joints. At cartilaginous joints, cartilages connect bones to one another.

  1. Which of these joints has a restricted range of motion?

a) Hinge joints 

b) Ball and socket joints 

c) Fibrous joints 

d) Cartilaginous joints 

Answer: d 

Explanation: Cartilaginous joints, such as those found between neighbouring vertebrae of the vertebral column, allow for limited mobility. Fibrous joints, such as those in the skull bones, do not enable any movement.

  1. Which of the following is a hinge joint?

a) Between the carpals 

b) Between carpal and metacarpal of thumb 

c) Knee joint 

d) Between atlas and axis 

Answer: c 

Explanation: The knee joint is an example of a hinge joint. It’s a synovial joint of some kind. The ankles, interphalangeal joints, and elbows all have hinge joints. It only permits movement on one axis.

  1. Which of the following is a saddle joint?

a) Between the carpals 

b) Knee joint 

c) Between carpal and metacarpal of thumb 

d) Between atlas and axis 

Answer: c 

Explanation: The saddle joint connects the carpal and metacarpal bones of the thumb. It is a synovial joint categorization. One of the two bones involved in the development of such a joint resembles a horse’s saddle.

  1. Which of the following is a pivot joint?

a) Between atlas and axis 

b) Between carpal and metacarpal of thumb 

c) Knee joint 

d) Between the carpals 

Answer: a 

Explanation: The pivot joint is a kind of synovial joint. It is located between the atlas and axis, which are the first and second vertebrae of the vertebral column, respectively. It’s also known as a rotary joint.

  1. Which of the following is a gliding joint?

a) Knee joint 

b) Between the carpals 

c) Between carpal and metacarpal of thumb 

d) Between atlas and axis 

Answer: b 

Explanation: The knee joint is an example of a hinge joint. The carpal and metacarpal of the thumb form a saddle joint. Between the atlas and the axis lies a pivot joint. Between the carpals lies a gliding joint.
