Cockroach External Morphology (Anal Cerci)
-
In both sexes of cockroach, a pair of jointed filamentous structures called anal cerci are present on:In both sexes of cockroach, the 10th abdominal segment bears a pair of jointed filamentous structures called anal cerci.
Types of Muscle Tissue and Their Locations
-
Three type of muscles are given as a, b and c. Identify the correct matching pair along with their location in human body.
(a) Striated, unbranched fibres bundled in parallel – skeletal muscle, e.g. triceps/biceps.
(b) Spindle-shaped, non-striated fibres – smooth muscle, found in the walls of internal organs such as the stomach and intestine.
(c) Striated, branched fibres with intercalated discs – cardiac muscle, found only in the heart.
So (a) Skeletal – Triceps, (b) Smooth – Stomach, (c) Cardiac – Heart.
Types of Epithelial Tissue and Example Locations
-
Match List-I with List-II regarding types of epithelium and their locations.
Pick the matching item from Column II for each row.
Column I
- A. Unicellular glandular epithelium
- B. Compound epithelium
- C. Multicellular glandular epithelium
- D. Endocrine glandular epithelium
Column II
- I. Salivary glands
- II. Pancreas
- III. Goblet cells of alimentary canal
- IV. Moist surface of buccal cavity
Correct answer: A → III, B → IV, C → I, D → II
Unicellular glandular epithelium – goblet cells of the alimentary canal Compound epithelium – lines the moist surface of the buccal cavity Multicellular glandular epithelium – salivary glands Endocrine glandular epithelium – pancreas (secretes hormones) Correct match: A-III, B-IV, C-I, D-II.
Cockroach Digestive System - Crop, Gastric Caeca, Malpighian Tubules, Gizzard
-
Match List-I with List-II regarding structures of the cockroach alimentary canal and their functions.
Pick the matching item from Column II for each row.
Column I
- A. The structures used for storing of food.
- B. Ring of 6-8 blind tubules at junction of foregut and midgut.
- C. Ring of 100-150 yellow coloured thin filaments at junction of midgut and hindgut.
- D. The structures used for grinding the food.
Column II
- I. Gizzard
- II. Gastric Caeca
- III. Malpighian tubules
- IV. Crop
Correct answer: A → IV, B → II, C → III, D → I
Crop – used for storing food Gastric caeca – ring of 6–8 blind tubules at the junction of foregut and midgut Malpighian tubules – ring of 100–150 yellow thin filaments at the junction of midgut and hindgut (excretion) Gizzard – used for grinding the food Correct match: A-IV, B-II, C-III, D-I.
