18 Questions
What is the basic unit of the nervous system?
Neurons
What is the function of the axon?
To transmit messages from the cell body to the dendrites of other neurons
What is the role of the synapse in the transmission of a neural signal?
The synapse releases neurotransmitters that convert the chemical signal back into an electrical signal
What is the primary function of sensory neurons?
To detect light, sound, color, taste, pressure, heat, and send messages about those to the brain
What is the primary function of motor neurons?
To transmit messages from the brain to the muscle to generate movement
What is the primary function of interneurons?
To connect spinal motor and sensory neurons
What is the role of dendrites in the transmission of a neural signal?
Dendrites carry impulses towards the cell body
What is the primary function of the cell body of a neuron?
To generate the electrical signal that is transmitted down the axon
Which type of hormones are made of fatty acids using cholesterol as a functional group?
Steroid hormones
Where is the pituitary gland located in the body?
Base of the brain, below the hypothalamus
What is the primary role of hormones in the body?
Acting like messenger molecules
Which part of the pituitary gland handles functions related to the kidney and breast?
Posterior pituitary
Which class of hormones is made up of amino acids joined by peptide bonds?
Peptides or Protein hormones
Which statement best describes the role of the endocrine system in maintaining homeostasis?
The endocrine system secretes hormones that regulate various bodily functions to maintain a stable internal environment.
What is the primary mechanism by which the endocrine system and the nervous system work together to maintain homeostasis?
Both systems use chemical signals to respond to changes that may disrupt homeostasis.
Which statement about the transportation of hormones is incorrect?
Hormones are transported exclusively through the lymphatic system.
Which of the following statements accurately describes the concept of homeostasis in the context of the endocrine system?
Homeostasis refers to the body's ability to maintain a relatively stable internal environment, despite external or internal changes.
Which of the following statements accurately describes the relationship between the endocrine system and the nervous system in maintaining homeostasis?
Both the endocrine system and the nervous system use chemical signals to respond to changes that may disrupt homeostasis, and they work together to regulate the activities of other systems.
