Which type of skeletal tissue has many open spaces which are filled with marrow?

A. Compact
B. Spongy

Explanation

Explanation
Spongy bone (also called cancellous bone) is characterized by a network of trabeculae (thin, interconnecting plates or beams) that create open spaces within the bone. These spaces are filled with bone marrow, which is involved in blood cell production. Spongy bone is typically found at the ends of long bones and in the interior of other bones, like the vertebrae.
In contrast, compact bone is dense and solid, with very few open spaces. It forms the outer layer of bones and provides strength and structure.

Which cell type is an immature cell for connective tissue proper?

A. Chondroblast
B. Chondrocyte
C. Fibroblast
D. Fibrocyte
E. Osteoblast
F. Osteocyte
G. Hemocytoblast
H. Hemocytocyte

Explanation

Explanation
The fibroblast is the immature cell in connective tissue proper. Fibroblasts are responsible for producing the components of the extracellular matrix, such as collagen and elastin fibers, and they play a crucial role in tissue repair and maintenance. As they mature, they become fibrocytes, which are less active and maintain the matrix.

Which of the following parts of the eye is the clear window of the eye?

A. Cornea
B. Lens
C. Iris
D. Retina
E. Choroid

Explanation

Explanation
The cornea is the clear, dome-shaped surface that covers the front of the eye. It acts as the "window" of the eye, allowing light to enter and helping to focus it as it passes through to the retina. The cornea provides most of the eye's focusing power and is transparent, which allows us to see clearly.

Which of the following terms represents the covering of a bone located in the medullary cavity?

A. Endosteum
B. Periosteum
C. Lacunae
D. Yellow marrow
E. Red marrow

Explanation

Explanation
The endosteum is the thin membrane that lines the inner surface of the bone, including the medullary cavity, which is the central cavity of long bones that contains bone marrow. The endosteum is important for bone growth, repair, and remodeling.

Which division of the nervous system is composed of nerves involved with the external environment and concerns skeletal muscles?

A. Central
B. Peripheral
C. Sensory
D. Motor
E. Somatic
F. Autonomic
G. Sympathetic
H. Parasympathetic

Explanation

Explanation
The somatic nervous system is a division of the peripheral nervous system that is responsible for voluntary control of skeletal muscles and for carrying sensory information from the external environment (e.g., touch, temperature, pain) to the central nervous system (CNS). It allows conscious control over movements such as walking, talking, and other voluntary actions.

Which of the following terms represents cells that break down/dissolve bone?

A. Osteogenic cells
B. Osteoblasts
C. Osteocytes
D. Osteoclasts

Explanation

Explanation
Osteoclasts are the cells responsible for breaking down and dissolving bone tissue. They perform a crucial role in bone resorption, the process where old bone is removed to allow for the formation of new bone. This activity is essential for bone remodeling and maintaining calcium balance in the body.

Which neuron structure receives impulses from surrounding neurons and sends impulses towards the cell body?

A. Nissl bodies
B. Axon hillock
C. Axon
D. Dendrites
E. Axon terminals

Explanation

Explanation
Dendrites are the tree-like branches of a neuron that receive impulses from surrounding neurons and transmit these signals towards the cell body. Dendrites are specialized for collecting information and play a crucial role in the transmission of electrical signals to the neuron’s cell body for processing.

When a person's blood sugar rises, insulin is released which causes blood sugar levels to fall. As blood sugar levels fall, the release of insulin stops. What type of homeostatic control mechanism is being described?

A. Positive
B. Negative

Explanation

Explanation
This is an example of a negative feedback mechanism. Negative feedback works to counteract a change and return the body to a stable state. In this case, as blood sugar levels rise, insulin is released to lower the blood sugar. When blood sugar levels fall to normal, the release of insulin stops, preventing further decrease. This process helps maintain homeostasis by keeping blood sugar within a narrow range.
Positive feedback mechanisms, on the other hand, amplify or reinforce the change, such as in the process of childbirth where contractions increase in intensity.

What is the unit for frequency?

A. Hertz
B. Decibel

Explanation

Explanation
The unit for frequency is hertz (Hz). Frequency refers to the number of cycles or vibrations of a wave per second. It is commonly used in the context of sound waves, electromagnetic waves (like light), and other periodic phenomena. One hertz is equal to one cycle per second.

10.

A. Sodium ions are inside the neuron and potassium ions are outside the neuron
B. Potassium ions are inside the neuron and sodium ions are outside the neuron
C. Sodium and potassium ions are inside the neuron
D. Sodium and potassium ions are outside the neuron

A. Sodium ions are inside the neuron and potassium ions are outside the neuron
B. Potassium ions are inside the neuron and sodium ions are outside the neuron
C. Sodium and potassium ions are inside the neuron
D. Sodium and potassium ions are outside the neuron

Explanation

Explanation
At rest, the neuron maintains a resting membrane potential due to the unequal distribution of ions across its membrane. The sodium (Na⁺) ions are primarily concentrated outside the neuron, while the potassium (K⁺) ions are concentrated inside the neuron. This distribution is maintained by the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell, using energy (ATP). This creates a resting potential of approximately -70 mV in most neurons. This ion distribution is essential for the generation of action potentials and proper nerve function.
