Cartilage, bone, adipose tissue and areolar tissue all secrete collagen or elastin fibres.
Blood is a fluid connective tissue that does not directly secrete collagen fibers.
Squamous epithelium lines blood vessel walls.
Ciliated epithelium lines Fallopian tubes.
Glandular epithelium = goblet cells of alimentary canal.
Compound epithelium lines pancreatic ducts.
Anal cerci are located at the base of the 10th abdominal segment in both male and female cockroaches.
Crop stores food (IV).
Gastric caeca are 6-8 blind tubules at foregut-midgut junction (II).
Malpighian tubules are 100-150 yellow filaments at midgut-hindgut junction (III).
Gizzard grinds food (I).
Unicellular glandular = goblet cells (III).
Compound epithelium = buccal cavity (IV).
Multicellular glandular = salivary glands (I).
Endocrine glandular = pancreas (II).
Statements a, b, d are correct.
Statement c is false (bone marrow produces blood cells).
Statement e is false (tendons attach bones to muscles, not to each other).
Hepatic caeca are responsible for secretion of digestive juices, not excretion.
Urecose glands, Malpighian tubules and fat bodies are excretory structures.
Crop and gizzard are found in birds. Pavo (Peacock), Psittacula (Parrot), Corvus (Crow) are all birds.
Neuroglia are supportive cells of nervous tissue, not connective tissue.
Blood, cartilage and adipose tissue are all connective tissues.
Tegmina (forewings) in cockroach arise from mesothorax. Hindwings arise from metathorax.
