Exam Q & As (Verified CORRECT
ANSWERS 2026
structure of skin - CORRECT CORRECT ANSWERS epidermis,
dermis, subcutaneous



burns - 3 degrees - CORRECT CORRECT ANSWERS partial thickness
- superficial , epidermis , 1

partial thickness- deep, epidermis & 1st half of dermis , 2

full thickness - epidermis & all dermis, 3



3 functions of skin - CORRECT CORRECT ANSWERS protection

temp regulation

sensation



skin sensory receptors found in - CORRECT CORRECT ANSWERS
dermis layer



body tissue types - CORRECT CORRECT ANSWERS nervous, muscle,
epithelial, connective



nervous tissue function - CORRECT CORRECT ANSWERS regulates
and controls body functions and activity



muscle tissue function - CORRECT CORRECT ANSWERS movement,
maintenance of posture, joint stabilization, heat generation

,epithelial tissue function - CORRECT CORRECT ANSWERS
protection, absorption, filtration, secretion, excretion



connective tissue function - CORRECT CORRECT ANSWERS bind,
support, protect, fill spaces, store fat, produce blood cells



skeletal muscle function - CORRECT CORRECT ANSWERS breathe,
maintain posture, move, speak, make facial expressions



muscles work by - CORRECT CORRECT ANSWERS shortening ,
contraction



skeletal muscle contracts in response to - CORRECT CORRECT ANSWERS
activation of the nervous system



contraction caused by - CORRECT CORRECT ANSWERS
neurotransmitters released by the nerve activates a cascade of events in each muscle fibre



skeletal muscle control type - CORRECT CORRECT ANSWERS
conscious



skeletal muscle made up of - CORRECT CORRECT ANSWERS muscle
cell / fibres



muscle cell/fibres made up of - CORRECT CORRECT ANSWERS
myofibrils

,myofibrils made up of - CORRECT CORRECT ANSWERS
myofilaments



thick myofilaments - CORRECT CORRECT ANSWERS myosin



thin myofilaments - CORRECT CORRECT ANSWERS actin



triggers muscle contration - CORRECT CORRECT ANSWERS calcium
released by sarcoplasmic reticulum



muscle shapes - CORRECT CORRECT ANSWERS fusiform, parallel,
unipennate, bipennate, multipennate, circular, convergent



fusiform muscle function - CORRECT CORRECT ANSWERS muscle
belly arranged parallel

greatest degree of shortening- quick and wide range of motion



parallel muscle function - CORRECT CORRECT ANSWERS fascicles
that run parallel to one another

parallel to the force generating axis, fast or extensive movements



unipennate muscle - CORRECT CORRECT ANSWERS fascicles are all
on the same side on the tendon

oriented at one fiber angle to the force-generating axis



bipennate muscle function - CORRECT CORRECT ANSWERS
Muscles that have fibers on two sides of a tendon

, multipennate muscle function - CORRECT CORRECT ANSWERS
Multipennate muscles have fascicles that insert on multiple tendons tapering towards a common
tendon, like multiple feathers converging on a central point.



circular muscle - CORRECT CORRECT ANSWERS muscle layer
encircling the body between the epidermis and longitudinal muscle layer

maintains constriction/ controls diameter



convergent muscle function - CORRECT CORRECT ANSWERS
ommon point of attachment, from which the muscle fascicles extend outward, not necessarily in a
specific spatial pattern, allowing the muscle to cover a broad surface

do not tend to exert as much force on their tendons



pennate muscle function - CORRECT CORRECT ANSWERS exert a
great deal of force for its overall size



Connective tissues

are characterised

by - CORRECT CORRECT ANSWERS specialised cells embedded in a
specialised "soup" or matrix



not all connective tissues are specialised for - CORRECT CORRECT ANSWERS
strength



loose connective tissue matrix made of - CORRECT CORRECT ANSWERS
Jelly-like, with collagen and elastic fibres in it



loose connective tissue cells that make and maintain matrix - CORRECT CORRECT ANSWERS
Fibroblasts
