The spinal cord terminates at the sacrum
The white matter of the brain is only found in the cerebellum
The left hemisphere of the cerebrum primarily controls the right side of the body
Damage to the primary somatosensory center of the brain will result in an inability to move skeletal muscles
Which statement is true regarding the skeletal system?
Flat bones are composed completely of compact bone
External stresses placed on bone (such as exercise) will decrease the bone matrix density
Red bone marrow is the site of hematopoiesis
Osteoclasts secrete collagen fibers to increase bone density
The nerve plexuses of the body allow for individual nerves to have axons from multiple nerve root levels.
The autonomic nervous system will innervate both internal organs and skeletal muscles.
Which endocrine hormone, in higher quantities, can suppress the function of the immune system and decrease inflammation of the body?
One of the main functions of the gyri and sulci is to allow for increased surface area of the cerebral cortex.
The cerebellum is primarily involved with conscious thought and emotions.
A ligament can reduce the friction of a tendon rubbing over a bone.
A ligament connects a muscle to a bone, while a tendon stabilizes a joint by connecting or joining one bone to another.
Which statement is true regarding skeletal muscle tissue?
Muscle cells have the exact same structure as cardiac muscle tissue
The neuromuscular junction is where the neurotransmitters are released and bind to the muscle cell
The muscle cells need little to no adenosine triphosphate (ATP)
The thick and thin filament permanently bind together to allow for muscle contraction to occur
Calcitonin will cause an increase activity in which of the following cells?
What statement is true regarding the peripheral nervous system (PNS)?
The efferent division of the PNS is transmits information from sensory receptors to the brain
The somatic division of the PNS refers to the innervation of the internal organs of the body
The ventral root of the spinal nerve transmits afferent information to the spinal cord
The autonomic nervous system is a branch of the visceral efferent division of the PNS
What statement is true regarding reflexes?
Neural integration (processing) of all reflexes occurs in the brain
The sensory neuron of a reflex arc transmit efferent impulses to the spinal cord
The Babinski’s test is testing a specific reflex of the lower motor neurons
The deep tendon reflex is commonly initiated with a reflex hammer in a neurological examination
Which bone cell is activated by calcitonin and is responsible for “building” bone tissue?
Damage to an upper motor neuron can cause a positive Babinski’s sign.
All of the following are symptoms of hypothyroidism, EXCEPT:
Dry and itchy skin
Increased heart rate
The spiral organ contains hair cells that form action potentials when stimulated to allow for the sense of smell to occur.
Which statement is true of dendrites?
They support the immune system of the nervous system
Most neurons have only one dendrite
They transmit information to other neurons and/or cells
They are the main input regions of the neurons
Which type of neuroglia cell forms myelin sheaths on axons within the peripheral nervous system?
Which statement is true of epiphyseal plates?
Found in the bone marrow region of long bones
If active, allows for continued longitudinal (lengthwise) growth of bone
Epiphyseal plates are not present in infants
Typically close around the age of 12 years of age
A neurotransmitter bound to a postsynaptic neuron membrane can initiate an action potential.
An increase in the level of thyroid hormone causing a decrease in TRH and TSH is an example of negative feedback.
Energy is created in which cellular organelle?
Smooth endoplasmic reticulum
Which of the following muscles is considered a rotator cuff muscle?
Both the epidermis and dermis contain blood vessels.
Which of the following statements is true regarding the eye?
The cornea provides the eye with the ability to adjust the amount of light coming into the eye
The region of the fovea centralis has a high concentration of cone cells
The blind spot of the eye has a high concentration of rod cells
The choroid of the eye is where the photoreceptor cells are found
The melanocytes are the most common cell in the epidermis and produce melanin.
Which of the following is not an effect of the parasympathetic nervous system?
Constriction of the pupils
Increased blood flow to the digestive system
Increased respiration rate
Decreased heart rate
The epidermis is composed of which type of tissue?
