Neurosecretory cells _____________
Select one:
a. are not connected to the nervous system.
b. do not typically produce action potentials.
c. release neurotransmitters into the blood.
d. transduce neural signals into endocrine signals.
NEUROSECRETORY CELLS
THE CORRECT ANSWER IS D) TRANSDUCE NEURAL SIGNALS INTO ENDOCRINE SIGNALS.
EXPLANATION
The neurosecretory cells are a type of neuron, whose main function is to translate the neural signals into chemical stimuli. There are some secretions called as neurohormones, which are released into the bloodstream to act like endocrine glands.
There are two main hormones that are secreted through these neurons.
OXYTOCIN
Oxytocin is a hormone released into the bloodstream for stretching or contraction of the cervix and uterus during labor or parturation, and also during breastfeeding.
VASOPRESSIN
When there is a reduction in the quantity of water in the body, this vasopressin or ADH (anti diuretic hormone) releases into the blood making the kidney to reabsorb water through the nephron in the distal convulated tubule.

The endocrine system has certain characteristics that set it apart from the nervous system. Which one of the following characteristics is typical of the endocrine system, but NOT the nervous system? A. Hormones rely on cell receptors to transfer a message, but neurotransmitters do not require them. B. The chemicals used for communication reach nearly every living cell except brain and reproductive tissues. C. Hormones can interact with the neurons, but neurons cannot communicate with endocrine cells. D. Hormones typically...
Which statement describes a general feature of a nervous system? Select one: a. Sensory receptor cells transform electrical stimuli into environmental signals. b. Motor commands are sent out from the effectors to the CNS. c. Central interneurons integrate signals from sensory receptors and other signals arising within the animal, generating an integrated pattern of impulses. d. Interneurons are collected into integrated areas at one end of the body rather than randomly dispersed.

Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
Which of the following statements about tissues is NOT true? Select one: a. Connective tissue consists of cells scattered throughout extracellular matrix that holds tissues & organs together and includes, cartilage, bone, and adipose tissue b. Muscle tissue includes striated/skeletal tissue that moves skeleton, cardiac tissue that controls heart contractions, and smooth tissue that line organs c. Epithelial tissue functions to provide a barrier against mechanical injury, pathogens, and fluid loss d. Nervous tissue includes dendrites that release neurotransmitters, the...
Neurons are electrically excitable cells in the nervous system that function to process and transmit information from one part the body to another, through specialized connections called synapses. The signaling process is partly electrical and partly chemical. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves. Neurons carry messages in the form of electrical signals called nerve impulses or action potentials. An action potential occurs when the resting membrane potential at a specific...
One function of glial cells is to a) increase the speed of neural impulses. O b) provide nutrients to neurons. c) stimulate the production of hormones. d) mimic the effects of neurotransmitters.
