PHYSIOLOGY & BIOLOGICAL PRINCIPLES
1. Which bone is known as the lateral malleolus in the leg?
Femur
Fibula
Tibia
Patella
2. Describe the significance of the central sulcus in the anatomy of the
cerebrum.
The central sulcus is involved in the regulation of body temperature.
The central sulcus connects the temporal lobe to the occipital lobe.
The central sulcus is a major blood vessel in the brain.
The central sulcus separates the frontal lobe from the parietal lobe
and is important for distinguishing between motor and sensory
areas.
3. The lower leg bone that makes up the lateral malleolus is the:
Talus
Calcaneus
Fibula
Tibia
4. Describe the role of the oculomotor nerve in eye movement.
The oculomotor nerve is involved in the sensation of touch in the eye.
, The oculomotor nerve regulates the secretion of tears.
The oculomotor nerve transmits visual information from the retina to
the brain.
The oculomotor nerve is responsible for controlling most of the
eye's movements, including the constriction of the pupil.
5. Bone-building cells and types of bone cells are primarily responsible for
secreting matrix during ossification process are called
osteoblasts
chondrocytes
osteocytes
osteoclasts
6. Describe the role of the fibula in the leg's structure and its significance in
relation to weight-bearing.
The fibula is responsible for muscle attachment only.
The fibula connects the knee to the ankle joint.
The fibula is a slender bone that does not bear weight but provides
lateral stability to the ankle.
The fibula is the primary weight-bearing bone in the leg.
7. Describe the composition of a hip bone and its significance in human
anatomy.
Each hip bone is formed from four bones that enhance mobility in the
lower body.
Each hip bone is made of five bones that protect the abdominal
organs.
, Each hip bone is made up of three separate bones, which are crucial
for supporting the pelvis and connecting the lower limbs to the
trunk.
Each hip bone consists of two bones that provide flexibility to the
pelvis.
8. In which layer of the skin does fat accumulation primarily occur when
someone gains weight?
Stratum corneum
Epidermis
Dermis
Hypodermis
9. If a muscle fiber is damaged, which connective tissue layer would be most
directly involved in the repair process?
Fascia
Epimysium
Endomysium
Perimysium
10. Describe the role of cerebrospinal fluid in the central nervous system.
Cerebrospinal fluid cushions the brain and spinal cord, providing
protection and maintaining homeostasis.
Cerebrospinal fluid transports oxygen to brain cells.
Cerebrospinal fluid aids in the digestion of nutrients.
Cerebrospinal fluid is responsible for transmitting nerve impulses.
, 11. Yellow bone marrow is found in the:
Diaphysis
Periosteum
None of the above
Epiphysis
12. In which specific layer of the epidermis does cell division primarily take
place?
Stratum corneum
Stratum granulosum
Stratum basale
Stratum spinosum
13. Describe the role of the synaptic cleft in neurotransmission.
The synaptic cleft allows neurotransmitters to be released from the
presynaptic neuron and bind to receptors on the postsynaptic
neuron.
The synaptic cleft serves as a barrier preventing neurotransmitters
from crossing.
The synaptic cleft is where electrical impulses are generated.
The synaptic cleft is involved in the production of hormones.
14. In a resting state, actin-myosin binding sites are covered by
tropomyosin
troponin
