Ribosomes are made in the...?
৩.
Function of smooth ER
৪.
Criteria of smooth muscle fiber excludes
ব্যাখ্যা
Smooth muscle fibers are individual small, fusiform (tapering) cells, linked by numerous gap junctions.Thin and thick filaments in smooth muscle fibers do not form sarcomeres, and no striations are present. Branching is absent.
৫.
Organelle that contains hydrolytic digestive enzymes
৬.
Osteocytes are found in
ব্যাখ্যা
Osteocytes (Gr. osteon, bone + kytos, cell), which are found in cavities (lacunae) between bone matrix layers (lamellae), with cytoplasmic processes in small canaliculi (L. canalis, canal) that extend into the matrix
৭.
Which cytoskeletal component participates in muscle contraction?
৮.
Which cytoskeletal component stabilize junction between cells?
৯.
Intramembranous ossification mainly occurs in
ব্যাখ্যা
Intramembranous ossification, by which most flat bones begin to form, takes place within condensed sheets (“membranes”) of embryonic mesenchymal tissue. Most bones of the skull and jaws, as well as the scapula and clavicle, are formed embryonically by intramembranous ossification.
১০.
Longest phase of cell cycle
১১.
DNA replication occurs in which phase of cell cycle?
১২.
Collagen type of Sharpey fiber
ব্যাখ্যা
Periosteum is a layer of dense connective tissue on the outer surface of bone, bound to bone matrix by bundles of type I collagen called perforating (or Sharpey) fibers.
১৩.
Type of epithelium in developing ovarian follicle
১৪.
Which type of stratified epithelium helps in maintaining distensibility?
১৫.
Keratinized stratified Squamous epithelium
১৬.
Simple coiled tubular gland is present in
১৭.
Compound acinar gland is present in
১৮.
Where duct is usually short or absent?
১৯.
Most common cell in connective tissue proper
ব্যাখ্যা
Fibroblasts are the most common cells in connective tissue proper, produce and maintain most of the tissue’s extracellular components. Fibroblasts synthesize and secrete collagen (the most abundant protein of the body) and elastin, which both form large fibers, as well as the GAGs, proteoglycans, and multiadhesive glycoproteins that comprise the ground substance.

২১.
Which one is immature bone?
২২.
Patella is related to tendon of
ব্যাখ্যা
Patella | Quadriceps femoris |
Pisiform | Flexor carpi ulnaris |
1st metatarsal | Flexor hallucis brevis |
২৩.

২৫.
Muscle fascicle is covered by
২৬.
Intercalated disc is present in which type of muscle fiber?
২৭.
Differentiated cells of which tissue cannot undergo mitosis?
ব্যাখ্যা
Most tissues undergo cell turnover with slow cell division and cell death. Nerve tissue and cardiac muscle are exceptions because their differentiated cells cannot undergo mitosis.
২৮.
What type of epiphysis is present in coracoids process of scapula?
২৯.
Uniaxial joint
ব্যাখ্যা
Uniaxial- elbow
Biaxial- wrist
Multiaxial- shoulder/hip
Biaxial- wrist
Multiaxial- shoulder/hip
৩০.
Bone remodelling cell
ব্যাখ্যা
Osteoclast helps in bone remodelling by bone resorption activity.
৩১.
Which type of epithelium has umbrella cell?
ব্যাখ্যা
Unique transitional epithelium or urothelium lines much of the urinary tract, extending from the kidneys to the proximal part of the urethra, and is characterized by a superficial layer of large, dome-like cells sometimes called umbrella cells.
৩২.
Anchoring junctions are produced by
ব্যাখ্যা
Adherent or anchoring junctions, formed by interacting proteins of the cadherin family, are points of strong attachment holding together cells of the epithelium.
৩৩.
Stereocillia are found in
ব্যাখ্যা
Stereocillia are long microvilli with specialized mechanosensory function in cells of the inner ear and for absorption in tissues of the male reproductive tract.
