1) Identify the correct procedure(s) in the dressing of a carcass?
a) Singeing precedes scalding.
b) Evisceration starts from the anterior end of the carcass and proceeds to the posterior for
all red meat species.
c) The head is left on lambs.
d) For the 4 species slaughter labs, a scalding procedure was only used in pigs.
e) Fisting in sheep replaces hide removal in cattle.
2) Which of the following best describes organization of the neuron?
a) Neuroglial cells transmit electrical impulses to the soma.
b) An efferent neuron will transmit information to the brain.
c) Saltatory conduction involves electrical impulses jumping from one Schwann cell to
another.
d) Axons conduct nerve impulses to the soma.
e) Information transfer will be faster in myelinated versus unmyelinated nerve fibres.
3) Which of the following is true regarding stunning?
a) This is the technique commonly used to kill the animal.
b) Stunning of cattle is usually performed using carbon dioxide in North America.
c) Captive bolt stunning is not used for market weight pigs.
d) Stunning usually kills the animal but packing plants include exsanguination to ensure that
death occurs.
e) All red meat species (beef, pork, lamb) are usually stunned using captive bolt.
4) Which of the following statements is true regarding development of rigor?
a) Onset of the rapid phase is dependent on depletion of Ca+2 in the muscle.
b) Sarcomere length will decrease while permanent crossbridges will increase as the muscle
develops full rigor.
c) Muscle will be quite extensible during the final postrigor phase.
d) Extensibility will be quite high while ATP is low during the delay period.
e) ATP is being rapidly depleted in the delay period.
5) Which of the following is accurate regarding differences and similarities between the
endocrine and nervous systems?
a) The rate of response to the chemical message is rapid for both systems.
b) The target tissues for both systems are identical.
c) The respective messengers from both systems can travel long distances to cells and
tissues all over the body.
d) One system uses the synapse while the other uses the bloodstream for messenger
delivery.
e) While neurons are used to produce the chemical messenger in one system, only endocrine
glands can be used to produce the chemical messenger in the other system.

6) The bones in the human hand between the wrist and knuckles correspond to these bones in
cattle and sheep?
a) Metacarpals or cannon bone.
b) Metatarsals.
c) Phalanges or cannon bone.

e) Carpals or cannon bone.
7) Posture is maintained by this part of the brain:
a) Pituitary.
b) Cerebellum.
c) Thalamus.
d) Medulla oblongata.
e) Cerebrum.
8) Identify the false statement about electrical stimulation of the carcass:
a) Accelerates development of rigor mortis.
b) Uses low voltage stimulation when processing carcasses entering the chill cooler.
c) Enhances the activity of the calpain enzymes, the enzymes responsible for improvements in
tenderness with postmortem ageing of the carcass or muscle cuts.
d) Is never used on pork.
e) Improves beef tenderness and flavour.
9) Which of the following is a proper procedure used in the dressing of a carcass?
a) Removal of the cannon bone in pigs.
b) Use of fisting in poultry.
c) Removal of the oil glands from pigs.
d) Removal of the kidneys before carcass weighing in sheep.
e) Removal of the kidney fat in cattle.
10) Which of the following accurately describes brain function or location?
a) The cerebellum is involved with learning, communication, and behavior.
b) The hypothalamus is part of the brain stem.
c) Thalamus provides sensory input information to the cerebellum.
d) The brain stem is involved with regulating blood vessel diameter.
e) The pons emerges out the foramen magnum as the spinal cord.
11) Which of the following accurately describes brain structures?
a) The cerebral cortex is made up primarily of white matter from nerve fibers.
b) Basal nuclei are directly underneath the cerebral cortex.
c) White matter serves to connect the cerebral cortex to other parts of the brain and spinal cord.
d) White matter refers to a layer of the brain made up primarily of nerve cell bodies.
e) Gyri and sulci refer to shallow and deep grooves respectively on the brain surface.
