- A.
Troponin
- B.
Actin
- C.
Tropomyosin
- D.
Ca++
- E.
Ca-
Correct Answer
B. ActinExplanation
A cross bridge is formed when myosin heads bind to actin. Actin is a protein that is part of the thin filaments in muscle fibers. When a muscle contracts, the myosin heads attach to the actin filaments and pull them closer together, causing the muscle to shorten. This binding of myosin to actin forms a cross bridge, which allows for the sliding of the thin and thick filaments, resulting in muscle contraction.Rate this question:

- D.
Motor neurons connect to interneurons, whereas sensory neurons do not.
Correct Answer
C. Motor neurons carry information away from the central nervous system, whereas sensory neurons carry information to the central nervous system.Explanation
Motor neurons and sensory neurons have different roles in the nervous system. Motor neurons carry information away from the central nervous system, transmitting signals from the brain and spinal cord to muscles and glands in the peripheral nervous system. On the other hand, sensory neurons carry information to the central nervous system, transmitting signals from sensory receptor cells (such as those in the skin, eyes, ears, etc.) to the brain and spinal cord for processing and interpretation. This distinction highlights the direction of information flow in these two types of neurons.Rate this question:

Formed by Schwann cells in the PNS?
- A.
Nodes of Ranvier
- B.
Unmyelinated Axons
- C.
Dendrites
- D.
Myelin Sheath
Correct Answer
D. Myelin SheathExplanation
The myelin sheath is formed by Schwann cells in the peripheral nervous system (PNS). It is a protective covering that surrounds and insulates the axons of neurons, allowing for faster and more efficient transmission of electrical signals. The myelin sheath is essential for the proper functioning of the nervous system, as it helps to prevent signal loss and interference. The nodes of Ranvier, on the other hand, are small gaps in the myelin sheath where the axon is exposed. Unmyelinated axons do not have a myelin sheath at all. Dendrites, on the other hand, are the branch-like extensions of neurons that receive signals from other neurons.Rate this question:

Information in neurons usually flows in what order?
- A.
Soma, dendrites, axon
- B.
Dendrites, soma, axon
- C.
Dendrites, myelin, axon terminals
- D.
Axon, soma, axon terminals
Correct Answer
B. Dendrites, soma, axonExplanation
Neurons are specialized cells that transmit information in the form of electrical signals. The information typically flows in a specific order within a neuron. Dendrites are the branch-like structures that receive signals from other neurons and transmit them to the soma, which is the cell body of the neuron. The soma integrates these signals and generates an electrical impulse. This impulse then travels down the axon, a long fiber-like structure, which transmits the signal away from the soma. Therefore, the correct order of information flow in neurons is dendrites, soma, and then axon.Rate this question:
