What is the correct list of examples of body's structures organized from the simplest to
the most complex?
ANSWER- Mitochondria, muscle cell, connective tissue, heart
Muscle cells contain many ___ because of their high metabolism of ATP.
ANSWER- Mitochondria
The failure of which of the following organs could interfere with gas exchange in the
body?
ANSWER- Lungs are involved in gas exchange.
Which of the following is located on the anterior region of the human body?
ANSWER- Patella is the anterior region.
Which of the following organelles is incorrectly paired with a function
ANSWER- Ribosome/ Production of ATP
Which of the following organelles is not involved in synthesis or packaging of proteins?
ANSWER- Lysosomes contain enzymes to break down macromolecules.
Which of the following types of tissue functions as a protective barrier?
ANSWER- Epithelial tissue serves as a protective barrier by lining body cavities and
covering body surfaces.
The skin is ______ to the bones.
ANSWER- superficial
______ neurons carry stimulus towards the central nervous system while __ neurons
carry impulses away from the central nervous system.
ANSWER- Motor; sensory.
Motor impulses are sent from CNS to a muscle; sensory impulses travel toward the
CNS.
Which of the following are incorrectly paired?
ANSWER- Spinal cord/ peripheral nervous system. The spinal cord is part of the central
nervous system.
The action of chewing food is controlled by the ____ division of the nervous system,
while the digestion of food is controlled by the ___ division of the nervous system.
ANSWER- Somatic; autonomic
Chewing is controlled by the voluntary somatic system; digestion is controlled by the
involuntary autonomic system.
, Which of the following is incorrect in relation to muscle contraction?
ANSWER- Both actin and myosin filaments shorten in length.
Transecting injuries to the spinal cord affect which of the following??
ANSWER- Both the somatic and autonomic system. The spinal cord carries signals to
and from the peripheral nervous system, which includes both somatic and autonomic
divisions. This disrupts communication with the brain affecting both systems depending
on the level of injury.
Which of the following parts of a neuron is incorrectly matched with its function?
ANSWER- Dendrite/receives stimulus from cell body.
A sarcomere ______.
ANSWER- Is the contracting unit of a muscle. Shortens in length when actin and myosin
slide past each other during contraction.
Which of the following muscle tissue types is voluntary?
ANSWER- Skeletal muscle is voluntary and is consciously controlled.
From the proper functioning of muscles, the cellular energy of ATP is ____.
ANSWER- needed for both muscle contraction and release.
Which of the following neuromuscular disorders affects both voluntary and involuntary
muscles?
ANSWER- Muscular dystrophy
The female gametes are called____ and contain a ____ set of chromosomes.
ANSWER- Ova/half
The females gametes are ova and contain a half set of chromosomes to complete the
full set necessary when fused with a sperm in fertilization.
Which of the following structures is part of both the male urinary and reproductive
system?
ANSWER- Urethra. The urethra is part of both the urinary and reproductive systems as
a shared pathway for urine and sperm expulsion.
Typically, egg and sperm meet for fertilization in which of the following?
ANSWER- Fallopian tube. Fertilization occurs normally in the fallopian tube.
Male gametes are produced in the ___ and mature in the ____.
ANSWER- Testes/ epididymis
The sperm are produced in the testes and mature in the epididymis.
In the female system, the hormone FSH stimulates _______, which LH stimulates
______.
