Question 1

The sex glands,which secrete hormones that regulate sexual development and behavior as well as reproduction,are called_________.

Accepted Answer

The gonads, including the ovaries and testes, are responsible for producing hormones that regulate sexual development, behavior, and reproduction. The other options listed do not have a primary role in regulating these functions.

Question 2

Researcher Roger Sperry won a nobel prize for his research on Epilepsy.Sperry cut through the ________ which joins the two hemispheres of the brain.

Accepted Answer

Roger Sperry won a Nobel Prize for his research on Epilepsy which involved severing the corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres of the brain. This procedure was done to prevent the spread of seizures from one hemisphere to the other.

Question 3

Mary suffered a head injury in a car accident last week.Since that time she is able to speak fluently but uses the wrong words when expressing herself.Mary may be exhibiting________ aphasia.

Accepted Answer

Mary's ability to speak fluently suggests that her motor skills for speech production are intact, but she is using the wrong words, indicating a problem with comprehension and word selection. This is characteristic of Wernicke's aphasia. Broca's aphasia involves difficulty with the motor production of speech, resulting in stuttering and difficulty forming words. Gall's and Korsakoff's are not types of aphasia.

Question 4

Which is not a specific function of the left hemisphere of the brain?

Accepted Answer

Pattern recognition is primarily associated with the right hemisphere of the brain.

Question 5

One function of the nervous system is to send information to and from all parts of the body.

Accepted Answer

This is true. The nervous system is responsible for transmitting information to and from every part of the body, including the brain, spinal cord, and nerves. This allows us to sense our environment, move our muscles, maintain homeostasis, and perform many other important functions.

Question 6

Which of the following is a function of the right hemisphere?

Accepted Answer

The right hemisphere is typically associated with processing visual-spatial information, perception of emotions, and recognition of patterns.

Question 7

Which of the following is the upper part of the brain consisting of two cerebral hemispheres and the structures that connect them?

Accepted Answer

The cerebrum is the upper part of the brain consisting of two cerebral hemispheres and the structures that connect them. The occipital lobe is the part of the brain responsible for processing visual information, the corpus callosum is the structure that connects the two cerebral hemispheres, and the cerebellum is the part of the brain responsible for motor control and coordination.

Question 8

Robert's mother is usually meticulous in her presentation.When picking her up for a family dinner,he noticed that her make-up was only applied to the right side of her face.Her hair was also brushed on the right side,but on the left it was matted and uncombed.He immediately took her to the hospital after she was unaware of any problems.She was diagnosed with ______,which is evidenced by damage to the association areas of the right hemisphere.

Accepted Answer

The symptoms described suggest spatial neglect, a condition where damage to the association areas of the right hemisphere cause a lack of awareness or attention to the left side of one's body or environment. This can result in uneven grooming, make-up application, and clothing choices. Wernicke's aphasia and Broca's aphasia are language-related disorders, and split-brain refers to a surgical procedure that cuts the corpus callosum connecting the two hemispheres of the brain.

Question 9

If Darren's brain is like that of most people,then language will be handled by his ________.

Accepted Answer

The left hemisphere of the brain is typically responsible for language processing in most people, so if Darren's brain is like that of most people, language would be handled by his left hemisphere.

Question 10

Tim is overweight.His physician has decided to test him to see if there is a problem with the regulation of his metabolism.Which endocrine gland will be the focus of diagnostic testing?

Accepted Answer

The thyroid gland regulates metabolism and can be tested to see if it is functioning properly. Being overweight can be a sign of an underactive thyroid, which can lead to a slower metabolism.

Question 11

_______________ are fired when an animal performs an action or when the animal observes that same action being performed.For example,an infant will mimic the facial expressions of adults.

Accepted Answer

Mirror neurons are fired when an animal performs an action or when the animal observes that same action being performed. This is why an infant will mimic the facial expressions of adults.

Question 12

Hormones are chemicals that are secreted and go directly into ________.

Accepted Answer

Hormones are secreted by glands and released directly into the bloodstream where they travel to target organs or tissues to exert their effects.

Question 13

Which is not a specific function of the right hemisphere of the brain?

Accepted Answer

Analysis of detail is a specific function of the left hemisphere of the brain. The right hemisphere is more involved in processing spatial relationships, creativity, and recognition of emotions.

Question 14

Endocrine glands___________.

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream to be transported to target organs or tissues.

Question 15

Hormones are___________.

Accepted Answer

Hormones are chemicals released into the bloodstream by the endocrine glands. The other options are incorrect as female and male gonads refer to the ovaries and testes respectively, and neurotransmitters are the chemicals found in synaptic vesicles that have an effect on the next cell.

Question 16

Which endocrine gland controls all of the other endocrine glands?

Accepted Answer

The pituitary gland is often referred to as the "master gland" because it secretes hormones that control the function of other endocrine glands in the body.

Question 17

The axon receives messages from other neurons.

Accepted Answer

The axon sends messages to other neurons, while the dendrites receive messages from other neurons.

Question 18

The ________,located on the top of the kidneys,secrete(s)hormones that regulate salt intake,control stress reactions,and provide a secondary source of sex hormones affecting the sexual changes that occur during adolescence.

Accepted Answer

The adrenal glands, located on the top of the kidneys, secrete hormones that regulate salt intake (aldosterone), control stress reactions (cortisol), and provide a secondary source of sex hormones affecting the sexual changes that occur during adolescence (androgens). The thymus gland is responsible for the development of T-cells for the immune system. The thyroid gland regulates metabolism. The gonads (testes in males and ovaries in females) produce primary sex hormones.

Question 19

Denise just received the results of a complete physical that found her body is not producing enough insulin.Which of the following endocrine glands is affecting her body's ability to produce insulin?

Accepted Answer

The pancreas is responsible for producing insulin, which regulates blood sugar levels in the body. If the body is not producing enough insulin, it is likely due to an issue with the pancreas. The adrenal gland regulates stress hormones, the thymus gland helps in the development of the immune system, and the thyroid gland regulates metabolism.

Question 20

The hormone released by the pineal gland that reduces body temperature and prepares you for sleep is ______.

Accepted Answer

The hormone released by the pineal gland that reduces body temperature and prepares you for sleep is melatonin.
