HUBS 191 Progress Test 1
Questions with Detailed Verified
Answers
What makes up the axial skeleton? Ans: skull, vertebral column, rib cage
What is recruitment? Ans: activating more motor units to make more force
What are flat bones? Ans: Thin plates of compact bone - some cancellous
What are flat bones used for? Ans: protection and muscle attachment
What are irregular bones? Ans: Variable in shape size and function
What is depolarisation? Ans: Membrane potential becomes less negative
what causes depolarisation? Ans: Na+ enters the cell
What are the features of the saddle joint? Ans: - biaxial
- flexion and extension
- abduction and adduction
- circumduction
- opposition
- e.g. carpometacarpal joint (thumb)

What does skeletal muscle do? Ans: - develop force
- control posture
- resist movement of joints
- under voluntary control
- provide support and protection for soft internal organs
- voluntary control over major openings
- converts energy (in part) to heat to maintain core temperature
- provide a major store for energy and protein
What is membrane potential typical value? Ans: -70mV
What maintains the membrane potential? Ans: sodium potassium pump
what does a neutraliser muscle do? Ans: eliminate an unwanted movement
caused by another muscle
What is hypotonic? what does it cause? Ans: too much water in ECF causes
cell to swell
what is a continuous variable? Ans: a variable that can take on any value
where is the pubis located? Ans: anterior aspect of the pelvic girdle
articulates with the other pubis to form the pubic symphysis
, 3|Page
what is the structure of fibrocartilage? Ans: collagen fibres form bundles
throughout matrix
orientation of fibres align with stresses
function is to resist compression and tension
what is plantar flexion? Ans: toes pointing to the ground
how is contraction of a muscle terminated? Ans: Ca2+ levels fall in sarcoplasm
what is a categorical variable? Ans: can summarise variables into categories or
groups
what is inversion of the foot? Ans: sole of foot faces towards midline
what are the features of the ball and socket joint? Ans: - multiaxial
- flexion and extension
- abduction and adduction
- circumduction
- rotation
- e.g. shoulder and hip
what are the conditions of the 2008 Human Tissue Act? Ans: 1. voluntary
donation of bodies
2. requires dual signed consent by donor and immediate family member
