1. Which organelle is the site of ATP production via oxidative phosphorylation?
A) Ribosome
B) Mitochondrion
C) Nucleus
D) Peroxisome
B) Mitochondrion
Mitochondria house the electron transport chain and ATP synthase,
producing most of the cell’s ATP through aerobic respiration.
2. Which tissue type is specialized to contract and produce movement?
A) Epithelial
B) Connective
C) Muscle
D) Nervous
C) Muscle
Muscle tissue contains actin and myosin filaments that enable contraction; it
includes skeletal, cardiac, and smooth muscle.
3. Which layer of the epidermis contains actively dividing stem cells?
A) Stratum corneum
B) Stratum lucidum
C) Stratum granulosum
D) Stratum basale
D) Stratum basale
, The stratum basale (basal layer) contains keratinocyte stem cells that
continually divide to replenish the epidermis.
4. The dermis is primarily composed of which type of connective tissue?
A) Adipose
B) Dense irregular connective tissue
C) Hyaline cartilage
D) Reticular connective tissue
B) Dense irregular connective tissue
The dermis contains collagen and elastic fibers arranged irregularly,
providing strength and elasticity.
5. Which bone articulates with the tibia to form the knee joint?
A) Fibula
B) Patella
C) Femur
D) Calcaneus
C) Femur
The distal femur articulates with the proximal tibia, forming the knee joint;
the patella is a sesamoid bone anterior to the joint.
6. What type of vertebrae are found in the neck region?
A) Thoracic
B) Lumbar
C) Cervical
D) Sacral
C) Cervical
The cervical vertebrae (C1–C7) are located in the neck and have transverse
foramina.
7. The axial skeleton includes all of the following except:
A) Skull
B) Sternum
C) Scapula
D) Vertebral column
, C) Scapula
The scapula is part of the appendicular skeleton (pectoral girdle), while the
skull, sternum, and vertebrae belong to the axial skeleton.
8. Which muscle contraction is involuntary and nonstriated?
A) Skeletal muscle
B) Cardiac muscle
C) Smooth muscle
D) All muscles are striated
C) Smooth muscle
Smooth muscle lacks striations, is under involuntary control, and is found in
walls of hollow organs.
9. The neurotransmitter dopamine is mainly associated with which brain
pathway?
A) Reward and motor control
B) Sensory perception
C) Auditory processing
D) Balance
A) Reward and motor control
Dopamine plays a key role in the brain’s reward system and in regulating
movement; its degeneration is linked to Parkinson’s disease.
10.The medulla oblongata controls:
A) Vision
B) Higher reasoning
C) Heart rate and breathing
D) Memory
C) Heart rate and breathing
The medulla oblongata contains cardiac, respiratory, and vasomotor centers
that regulate vital autonomic functions.
11.The functional connection between a motor neuron and a muscle fiber is
the:
A) Synaptic cleft
