Question

All of the following are connective tissues, except
(1) Blood (2) Neuron
(3) Bone (4) Tendon

Answer 1

Answer:

The correct option is Option B i.e. Neuron.

Option B

Explanation:

• Blood is a modified connective tissue, originating from embryonic mesoderm, and having more matrix i.e. plasma than corpuscles.
• Bone is also a connective tissue originating from the embryonic mesoderm, and having more calcium phosphate matrix than the Osteocytes.
• Tendon is connective tissue, mainly formed of yellow and collagen fibres and originates from mesoderm.
• But, neuron is structural and functional unit of  Nervous System. It originates from ectoderm.

Answer 2

Answer: (2) Neuron

Connective tissues are most abundant and widely distributed in the body of complex animals, they are named so because of their special function of linking and supporting other tissues and organs of the body.

Blood - is a fluid fluid connective tissue containing plasma, RBC, WBC and platelets.

Bone - have a hard and non pliable ground sunstance rich in calcium salts and collagen fibres.

Bone and Blood , both are specialised connective tissue.

Tendon- attach skeleton muscles to bone and it comes under dense connective tissue.

Neuron- is the structural and functional unit of the nervous system and not the connective tissue.
