What are the 3 categories of endocrine signaling? -
Answer-1. Long distance signaling
2. Local signaling
3. Signaling that overlaps with nervous system
components to transport ligands to cells
What are the 5 types of signaling? - Answer-endocrine,
paracrine, autocrine, synaptic, neuroendocrine
endocrine signaling - Answer-Form of long-distance
signaling where ligands are released and travel through
blood to reach a target cell, which could be anywhere is
the body.
What does endocrine signaling play a role in? - Answer-
Regulatory processes such as maintaining blood pressure,
blood volume, and energy metabolism
,2|Page
Regulatory mechanisms such as growth, sexual
maturation, and reproduction.
paracrine signaling - Answer-Form of local signaling where
ligands are released near target tissues and move by
diffusion. NOT transported through blood.
autocrine signaling - Answer-Form of local signaling where
the cell releasing the ligand is also the target cell of the
very same ligand. NOT transported through blood.
synaptic signaling - Answer-Form of local signaling where
the ligands are released from a pre-synaptic neuron into
the synaptic cleft and will eventually bind to the post-
synaptic cell. diffuses across a synapse.
Target cells of synaptic signaling - Answer-Cells
comprising Muscle, tissue, or glands
neuroendocrine signaling - Answer-Form of long-distance
signaling where ligands are released from a neuron into
the bloodstream where they bind to target cells.

Hormones - Answer-chemical messengers that are
manufactured by the endocrine glands, travel through the
bloodstream, and act as signaling molecules.
What does the endocrine system consist of? - Answer-
Glands, organs and tissues that are responsible for the
regulation and coordination of allother body systems.
What specifically is the endocrine system responsible for
(8)? - Answer-1. Water balance
2. Ion regulation
3. Growth and metabolism
4. Heart rate and blood pressure
5. Blood glucose regulation
6. Reproductive functions
7. Uterine contractions during labor
8. Milk and release post labor
How does the endocrine system exert control (2)? -
Answer-1. Various types of signaling
2. Chemical ligands
, 4|Page
What do hormones do? - Answer-Maintain homeostasis
and regulate many physiological responses
Public health - Answer-Focuses on the health of
populations
Population - Answer-Broad term that may refer to people
within a certain geographic location, a specific nationality
or race, or those with unique characteristics, such as the
homeless, those infected with HIV or marginalized
persons.
Epidemiology - Answer-Study of how disease is distributed
within a population and the identification of the factors that
determine that distribution.
Basic Objectives of Epidemiology - Answer-1. Identifying
the cause of a disease and important risk factors
2. Determining the burden of disease
3. Studying the natural history of a disease
4. Evaluating preventative and therapeutic models
4. Developing public policy
