Question

A section of a human tissue was stained and

studied under the microscope. Upon observation,

numerous yellow elastic fibres were found

scattered between chondrocytes in lacunae but

lamellae were absent. Few white fibres were also

present. This tissue could have been taken from

(1) Intervertebral disc (2) Tracheal wall

(3) Articular cartilage (4) Pinna of ear​

Answer 1

Answer:

THIS TISSUE IS TAKEN FROM ARTICULAR CARTILAGE.(Because cartilage cells are called as chondrocytes).

Option 3) is correct.

Answer 2

This tissue could have been taken from Pinna of ear​. (Option 4)

• Several components are visible when looking at an ear specimen under light microscope.
• The external ear's keratinized stratified squamous epithelium and underlying cartilaginous structure can be seen in a cross-sectional sample, along with possible cerumen-producing gland visibility.
• The non-keratinized stratified squamous epithelium of the middle ear will be visible.
• The inner ear will be the most intricate structure that a lens can reveal.
• A histological study of the cochlea, membranous labyrinth, organ of Corti, kinocilium, stereocilia, semicircular canals, and stereocilia may be performed.
• Two fluid-filled pathways, the spiral ganglion, the organ of Corti, and bone can all be seen in a straightforward cross-section of the cochlea.
• The spiral ganglion neurons, hair cells, pillar cells, Boettcher cells, Claudius cells, and Deiters cells are among the highly specialised inner auditory cells. (phalangeal cells)

Hence, the tissue could have been taken from Pinna of ear​.
