Multiple choice evs bones joints in the human body our skeletal system and the skin joints

Cavity into which the head of longest and strongest bone of human body fits is

  1. Glenoid

  2. Clavicular

  3. Obturator foremen

  4. Acetabulum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The longest bone in the human body is the femur bone also called the thigh bone. It is located in the anatomical position just below the pelvic girdle in articulation with the acetabulum thereby forming the hip joint proximally and in articulation with the proximal parts of the tibia and fibula bones below the patella region, distally.

So, the correct answer is 'Acetabulum'.

Correct the given statements by replacing the underlined words and select the correct option.


(i)  The hinge joint is present in our neck.
(ii)  The number of bones in our appendicular skeleton is 140.
(iii) The number of bones present in the vertebral column in human 36. 

(iv) The complete bowling action in cricket is possible because our arm is joined to our shoulder by a pivot joint.

  1. (i) Ball and socket joint, (ii) 140, (iii) 33, (iv) Hinge joint.

  2. (i) Fixed joint, (ii) 126, (iii) 33, (iv) saddle joint.

  3. (i) Pivot joint, (ii) 126, (iii) 26, (iv) Ball and socket joint.

  4. (i) Pivot joint, (ii) 130, (iii) 26, (iv) Ball and socket joint.

C Correct answer
Explanation

i) In our neck cervical vertebrae form joints which are pivotal joints.

ii) Each appendage has 30 bones so the appendicular skeleton has less the 140 bones.
iii) Number of bones in the vertebral column are 26 and not 36.
iv) Arm is joined to the shoulder not by a pivot but a ball and socket joint.
So, the correct option is (i) Pivot joint, (ii) 126, (iii) 26, (iv) Ball and socket joint.

The shoulder joint is formed between

  1. Clavicle and acromion process of scapula

  2. Clavicle and glenoid cavity of scapula

  3. Humerus and glenoid cavity of scapula

  4. Humerus and acromion process of scapula
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The shoulder joint, also known as an acromioclavicular joint is a joint at the top of the shoulder. It is the junction between acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. It is a plane synovial joint. This joint provides the ability to raise the arm above the head.

So, the correct answer is 'Clavicle and acromion process of scapula'.

Hinge joint allows ________ movement.

  1. Nonaxial

  2. Biaxial

  3. Uniaxial

  4. Multiaxial
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A hinge joint is a type of synovial joint that restricts movement to a single plane, allowing for angular movement in one direction, such as bending and straightening. Hence, it is classified as uniaxial.

Find the odd one out.

  1. Femur, radius, tibia, fibula & tarsals

  2. Humerus, ulna, metatarsals & phalanges

  3. Skull, vertebrae, sternum and pelvic gridle

  4. Hinge joint, ball & socket joint and sutures

  5. Humerus, femur, radius, tibia & teeth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • The forelimbs consist of the humerus, radius, ulna, carpals, metacarpals, and phalanges. 
  • It moves against or articulates with the scapula at the shoulder joint.
So, the correct option is 'Femur, radius, tibia, fibula & tarsals'

Example of hinge joint is

  1. Elbow joint

  2. Ankle joint

  3. Interphalangeal joint

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The hinge joint is a synovial joint, which permits uniaxial movement of bone about one axis of rotation. In hinge joint, convex surface of one bone fits into concave surface of another. The movements possible are flexion and extension. Example of hinge joints are elbow, interphalangeal joint, knee and ankle joints.

Articulation of ulna with humerus at the elbow joint is _________ joint.

  1. Hinge

  2. Pivotal

  3. Gliding

  4. Ball and socket
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Answer:
1.The elbow joint is a synovial hinge joint with two articulations.
2.The trochlea of the humerus articulates with the trochlear notch of the ulna, and the capitulum of the humerus articulates with the head of the radius.
So correct answer is option A.Hinge joint.
