QUESTIONS WITH SOLVED ANSWERS.
1. ball and socket joint - CORRECT ANSWER✅✅-round head in cup shaped cavity
-widest rand of motion
-multiaxial, plus rotation
-hip, shoulder
1. collagen (white) fibers - CORRECT ANSWER✅✅-thick threads of collagen, the body's main structural
protein
-great tensile strength and flexible, slightly elastic
-found in ligaments and tendons
1. compact bone - CORRECT ANSWER✅✅osteocytes+ matrix+ central canal = osteon
-osteons are cemented together to form compact bone
-central canals contain blood vessels
-bone is well nourished and heals faster than cartilage
-lamellae occur in rings around central canal
1. epithelial tissue - CORRECT ANSWER✅✅-protection, secretion, absorption, excretion
-cover body surface, cover and line internal organs, compose glands
-avascular (no blood vessels), cells readily divide, cells are tightly packed
*9 types and are classified by shape and layers*
1. hyaline cartilage - CORRECT ANSWER✅✅-cells in solid gel matrix
-supports, protects, provides framework
-ends of bones, nose, and rings in walls of respiratory passages
,1. papillary layer of dermis - CORRECT ANSWER✅✅-superficial layer
-areolar connective tissue
-thinner of the 2 layers
-location of dermal papillae
-form fingerprints
1. skeletal muscle tissue - CORRECT ANSWER✅✅-attached to bones
-STRIATED
-VOLUNTARY
-multinucleated cells
-long cylindrical cells
-stimulated by nerve cells
many nuclei
1. sutures (FJ) - CORRECT ANSWER✅✅-between flat bone of skull
-thin layer of connective tissue connects bone ( sutural ligament)
-synarthrotic (immovable)
1. Tight junctions - CORRECT ANSWER✅✅-membranes of adjacent cells merge and fuse
-located among cells that form linings, sheet like layers
-BLOOD BRAIN BARRIER
1) receptor - CORRECT ANSWER✅✅detects and provides information about the stimuli
1) Water - CORRECT ANSWER✅✅-most abundant substance in body
- environment for metabolic processes
-required for transport of substance
-regulation of body temperature
, 2. cardiac muscle tissue - CORRECT ANSWER✅✅-STRIATED
-INVOLUNTARY
-only in the heart
-branching cells
-intercalated disc
-central nucleus
2. condylar joint - CORRECT ANSWER✅✅-oval condyle fits into elliptical cavity
-back and forth, side to side movement
-biaxial movement, no rotation
-joint between metacarpals and phalanges
2. connective tissue - CORRECT ANSWER✅✅-bind, support, protect, fill spaces, store fat, produce blood
cells
-widely distributed throughout the body
-mostly have good blood supply (vascular), cells are farther apart than epithelial cells, with extracellular
matrix in between
2. Desmosomes - CORRECT ANSWER✅✅-form "spot welds" between cells
-structural reinforcement
*located among out skin cells*
2. elastic (yellow) fibers - CORRECT ANSWER✅✅-composed of elastin protein: branching
-can stretch and return to original shape
-not as strong as collagen fibers
-found in vocal cords, respiratory air passages
2. elastic cartilage - CORRECT ANSWER✅✅-cells in solid gel matrix
