Write the differences between dense regular connective tissues,and dense irregular connective tissues.

Read the following four statement (i) - (iv) having certain mistakes in two of them. (i) Adipose tissue is a type of dense connective tissue located beneath the skin (ii) Compound epithelium has extensive role in absorption and secretion (iii) Most of the cartilages in vertebrate embryos are replaced by bones in adults (iv) Smooth muscles are involuntary as their functioning cannot be directly controlled Which of the above statements have mistakes ?

Read of following statements regarding different types of animal tissues and select the incorrect ones. (i) Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium (ii) Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large bloood vessels (iii) Columnar epithelium present in gastric glands, intestinal glands, intestinal glands and pancreatic lubules, has a secretory role and is called as glandular epithelium (iv) Epithelial tissue arises only from the ectoderm of embryo and is usually supplied with blood vessels.

Identify the correct statements from the below. (I) Both stratified cuboidal and stratified columnar cells are more common in embryo as compared to adult. (II) Goblet cell is an unicellular exocrine gland. (III) Pancreas is a compound gland, made up of more than one type of secretary units. (IV) Vitamin-C is essential for the normal activity of connective tissues.

(a) Glisson's capsule - Duct's of parotids gland (b) Sphincter of oddi - Guard the opening of the ampulla of vater ("c") Goblet cells - Connective tissue (d) Gastric Regae - Longitndinal muscular cords

Consider the following four statements (i) - (iv) and select the correct option stating which ones are true (T) and which ones are false (F) (i) The epithelium of proximal convoluted tobule (PCT) of nephron in the kidney has microvilli (ii) Simple epithelium covers the dry surface of the skin, the moist surface of buccal cavity, pharynx, inner lining of salivary glands and of pancreatic ducts (iii) The wall of internal organs such as the blood vessels, stomach and intestine contains skeletal muscle (iv) Bone marrow in some bones is the site of production of blood cells.

Consider the following statements each with one or two blanks. (i)Each pectoral girdle consists of a (A) and (B) . (C) is a condition of rapid spasms (wild contractions) in muscle due to low Ca^(++) in body fuild. Each organised skeletal muscle in our body is made of a number of (D) held together by a common collagenous connective tissue layer called (E) . Which one of the following options correctly fills the blannks in any two the statements ?

Mark the odd one in each series: (a) Areolar tissue, blood, neuron, tendon (b) RBC, WBC, platelets, cartilage (c) Exocrine, endocrine, salivary gland, ligament (d) Maxilla, mandible, labrum, antennae (e) Protonema, mesothorax, metathorax, coxa
