  1. Only $1$
  2. Only $2$
  3. $1$ and $2$

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The humerus is the bone of the upper arm, not the leg. The stapes is indeed the smallest bone in the human body.

Study the following statements:
$1$. Study of bones is called Osteology.
$2$. Process of bone formation is known as Ossification.
$3$. Sesamoid bones are formed by ossification in tendons.

  3. $1$ and $3$
  4. $1$ and $2$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Osteology is the study of bones. Ossification is the process of bone formation. Sesamoid bones are small, round bones embedded in tendons.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Study the following statements:
$1$. Tendons connect bone to muscles.
$2$. Bone forming cells are osteoblasts.
$3$. Ligament connect bone to bone.
Which of the statements given are correct?

  1. $1$ and $2$
  2. $2$ and $3$
  3. $1, 2$ and $3$

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Tendons connect muscles to bones, ligaments connect bones to bones, and osteoblasts are indeed the cells responsible for bone formation. All three statements are biologically accurate.

Multiple choice general knowledge our skeletal system and the skin other systems in the body introduction to skeletal system busy at work - our internal organs

Bones of old persons are brittle and fractured more readily occur because they contain more _________.

  1. lacunae

  2. organic matter

  3. inorganic matter

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

Bone brittleness in the elderly is primarily due to a decrease in organic collagen content and an increase in the relative proportion of inorganic mineral salts, which makes the bones harder but less flexible.

Multiple choice evs - i busy at work - our internal organs other systems in the body introduction to skeletal system our skeletal system and the skin

Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone and the skull are joined by fibrous joint.

  2. First vertebrae is axis, which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A suture is a type of fibrous joint, which only occurs in the skull. These joints are synarthroses. One parietal bone is located on each side of the skull just behind the frontal bone. The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum.

Which of the following structures or materials is incorrectly matched with a tissue?

  1. Haversian system-bone

  2. Fibroblasts-skeletal,muscle

  3. Chondrin-cartilage

  4. Basement membrane-epithelium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A fibroblast is a type of cell that is responsible for making the extracellular matrix and collagen.

So, the correct option is 'Fibroblasts-skeletal,muscle'.

  1. A muscle with a muscle

  2. A muscle with a bone

  3. A bone with another bone

  4. A bone with a ligament
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tendons connect muscles to bones. They are a type of connective tissue. They are strong with limited flexibility.

Multiple choice botany classical genetics variation and its type natural selection introduction to genetics

Height in humans is

  1. Somatogenic variation

  2. Discontinuous variation

  3. Continuous variation

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

A.Somatogenic variation – These are acquired variations and non inheritable in nature. Eg:phenotypic plasticiy.

B.Discontinuous variations – These are responsible for the formation of a new species and the organism, thus, formed is called mutant. Eg:Mutations.

C.Continuous variations – These are fluctuating variations and cannot give rise to new species. Eg:Human height.

So, the correct option is ‘Continuous variations’.

Multiple choice biology locomotion and movements introduction to locomotion skeleton and joints movement in animals

Which of the following is not a biological function of skeleton?

  1. Support

  2. Storage

  3. Excretion

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

  • The human skeleton is the internal framework of the body.
  •  It is composed of around 270 bones at birth this total decreases to around 206 bones by adulthood after some bones get fused together. 
  • The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Excretion is not a biological function of the skeleton.
So, the correct answer is 'Excretion'.

Multiple choice zoology excretory system of human disorders of excretory system disorders related to the excretory system functions and disorders of kidney

Renal rickets are bending of weight bearing long bones in

  1. Infants

  2. Young children

  3. Adolescents

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

Rickets is a condition especially due to deficiency of vitamin D which results in weak and soft bones in children. In Elderly patients, Rickets that occur due to chronic renal insufficiency is called Renal rickets. Renal rickets is bending of weight-bearing long bones in Elderly Persons. Bones become weak which results in bending of bone because excess calcium is lost through urine due to renal insufficiency.

So, the correct answer is 'Elderly persons'.

Multiple choice zoology neural control and coordination structure and function of spinal cord the spinal cord spinal cord

The location of filum terminale is

  1. In the skull

  2. In the thorax

  3. In the lumbar vertebrae

  4. In the pelvic girdle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The spinal cord is the extension of the medulla oblongata that runs down through the foremen of magnum. The lowest part of the spinal cord is narrow and it is called the conus medullaris. The conus medullaris is present at the L$ _{1}$ vertebrae. The terminal part of the conus medullaris is a thread-like structure that is made up of fibrous connective tissue called the filum terminale. It is the non-nervous part of the spinal cord that can be seen in the lumbar vertebrae.

Hence, the correct answer is 'In the lumbar vertebrae'
