Glenoid cavity is associated with

  1. Scapula

  2. Humerus

  3. Femur

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • A pectoral girdle or shoulder girdle attach the bones of upper limb to the axial skeleton.
  • Each pectoral girdle is formed of two halves. Each half of pectoral girdle consists of a scapula and clavicle. 
  • Glenoid cavity is a shallow, pyriform articular surface, which is located on the lateral angle of the scapula. It articulates with the humerus to form the shoulder joint. Hence glenoid cavity is associated with scapula and humerus.
  • So,the correct answer is 'Both A and B'.

Humerus bone is present in the

  1. Upper arm

  2. Lower arm

  3. Lower jaw

  4. Thigh
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The humerus is the single bone of the upper arm region. It articulates with the radius and ulna bones of the forearm to form the elbow joint. Distally, the humerus becomes flattened. The much smaller lateral epicondyle of the humerus is found on the lateral side of the distal humerus.

So, the correct option is 'Upper arm'.

One of the following is a sesamoid bone in man?

  1. Periotic

  2. Ramus

  3. Clavicle

  4. Patella
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A bone embedded in the tendon is known as a sesamoid. They are usually found in the joints of the body. The patella in the knee of a man is the largest sesamoid bone present in the human body.
So, the correct answer is 'Patella'.

A curved bone is structurally designed to

  1. Accommodate easily in body

  2. Absorb the stress of the body weight at several different points so that the stress is evenly distributed

  3. Provide more area for attachment of muscles

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

 Long bones are longer than they are wide and they are slightly curved for strength.
– A bone that is curved is structurally able to absorb the stress of the body at several points so the stress will be evenly distributed.
– The straight bone would not be able to evenly distribute the weight of the body and the bone would break more easily.
– Long bones are shaped like tubes with rounded ends that are designed to fit into other bones to form joints.
– The ends of long bones are filled with spongy bone; this makes them light but strong.
– Long bones can be found in the thigh, lower leg, toes, arms, forearms and fingers.

A fracture in which a small piece of the bone is broken, but remains attached with the ligament is known as

  1. Green stick fracture

  2. Avulsion fracture

  3. Comminuted fracture

  4. Compound fracture
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

An avulsion fracture is an injury to the bone in a location where a tendon or ligament attaches to the bone. When an avulsion fracture occurs the tendon or ligament pulls off a piece of the bone and because of that the broken bone remains attached to the ligaments. So, the correct answer is 'Avulsion fracture'.

Compound fracture is characterised by

  1. Breaking and cracking of bone at different places.

  2. Breaking bone into more than two fragments.

  3. Appearance of a number of cracks in the same bone.

  4. Protrusion of broken end of bone.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • A fracture is a medical condition in which there is a partial or complete break in the continuity of the bone.
  • A compound fracture is characterized by breaking and cracking of bone at different places.
  • Food high in calcium, like milk, cheese and yogurt, will strengthen your bones. Strong bones can help prevent compound fractures.
  • So, the correct answer is 'Breaking and cracking of bone at different places'

A fracture in which one bone breaks into many parts and some of the pieces protrude out of injured skin is known as

  1. Green stick fracture

  2. Comminuted fracture

  3. Compound fracture

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

An open fracture or compound fracture is a fracture in which there is an open wound or break in the skin near the site of the broken bone. This wound is caused by a fragment of bone breaking through the skin at the time of the injury. So, the correct answer is 'compound fracture'.

Comminuted fractures are those in which

  1. A bone breaks into many pieces and some of the pieces are without blood circulation.

  2. A bone breaks into two parts.

  3. A bone breaks into many parts.

  4. A small piece of bone breaks.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • A fracture is a medical condition in which there is a partial or complete break in the continuity of the bone.
  • Comminuted fractures are those in which a bone breaks into many pieces and some of the pieces are without blood circulation.
  • These types of fractures occur after high impact trauma such as vehicular accidents.
  • These types of fractures take a minimum of 3 months to recover.
  • So, the correct answer is ''A bone breaks into many pieces and some of the pieces are without blood circulation'.

At times ligaments and tendons are overstretched or torn. The phenomenon is 

  1. Sprain

  2. Dislocation

  3. Fracture

  4. Tension
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The bands of fibrous tissue that connect bones to bones at joints are called as Ligaments and which connect muscles to the bones are called as tendons.
  • At times ligaments and tendons are overstretched or torn. The phenomenon is called a sprain.
  • Sprain happen most often in the ankle but can occur at any joint, such as the wrist or knee.”
  • So, the correct answer is a 'Sprain'.
Multiple choice zoology skeleton and movements disorders of musculoskeletal system disorders of muscle and skeleton joints and movements

Sprain involves

  1. Overstretching of ligament

  2. Overstretching of tendon

  3. Dislodging of bone

  4. Both A and B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A sprain is a stretching or tearing of ligaments which are the tough bands of fibrous tissue that connect two bones together in the joints. The most common causes of sprains are falling, twisting etc. These types of injuries may cause the joint to move out of its normal range of movement that causes the tearing or stretching of the ligament. So, the correct answer is 'Overstretching of ligament'.

Dislocation of bones occurs in persons who have met with and met in accidents due to the

  1. Tendon break

  2. Break of skeletal muscle

  3. Ligament break

  4. Areolar tissue break
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The ligament is the connective tissue which attaches two or more bones together to form a joint. When the ligament breaks, the two bones cannot be held together and dislocate. Generally, when the person met with an accident and the ligament is broken, there are chances that the person will suffer from the dislocation of the bones. 

Thus, the correct answer is option C.
