Nervous System Function
The division of the Nervous system that is composed of the brain and the spinal cord together
Central Nervous System (CNS)
The part of the brain responsible for conscious activities. (Includes frontal lobe, parietal lodge, occipital lobe and limbic lobe)
cerebrum
This part of your ear you can see. It has a flap of cartilage designed to collect sound waves.
outer ear
This part produces insulin and glucagon- insulin helps the blood cells absorb glucose from the blood and causes the liver to store glucose as glucagon.
pancreas
The main function of the endocrine system is to release ______ into the bloodstream.
hormones
This part gathers information from the sensory organs and processes it before relaying it to the CNS.
Thalamus
This part regulates involuntary activities like body temperature, blood volume and fluid balance, appetite and emotional expression. It is the link between the nervous system and the endocrine system.
hypothalamus
This part of the ear contains a series of channels and cavities. The cochlea receives vibrations and sends them to the nerves to go to the brain. The semicircular canals provide a sense of balance.
inner ear
The organ that connects the nervous system and the endocrine system. Its neurons produce hormones for the endocrine system.
hypothalamus
Hormones travel throughout the body to their ______ ______ where they bind to the cells.
target cells
fluid in the CNS that provides nutrition to the cells, cushion for the structures and removes waste.
cerebrospinal fluid
The part of the brain that connects the rest of the brain to the spinal cord and controls involuntary respiration, blood pressure, and heart rate.
brain stem
transparent part of the eye that allows light to enter
cornea
This part secretes hormones from the hypothalamus like growth hormones (determine a person’s size and height), and oxytocin (stimulates the smooth muscles to contract), also known as the master gland.
pituitary glands
Name one process of the body that hormones influence.
water balance in the blood, reproduction, growth, and blood pressure
the functional unit of the nervous system, made up of a cell body, dendrites and an axon.
neuron
The part of the cerebrum that performs mental functions like reasoning, planning and memorizing and controls verbal communication and starts the commands for voluntary body movements.
frontal lobe
Part of the eye with neurons and fibers that are stimulated by light (photoreceptors)
retina
Located in front of the trachea, this part produces thyroxine (controls the speed of the cells, increases oxygen use, stimulates heat production and affects growth) and calcitonin (responsible for moving excess calcium from the blood to the bones.)
thyroid
In order to keep a healthy balance of hormones, the ______ (organ) breaks down hormones and the kidney excretes them so that they do not take over and cause our bodies to run out of control.
liver
Type of Efferent NS that activates skeletal muscles and can be controlled voluntarily.
Somatic Nervous System
The part of the cerebrum that perceives the sensation of hearing and smell. It also stores memories of sights and sounds.
temporal lobe
Which sense does our body accommodate or adjust to the quickest?
sense of smell
This part produces epinephrine and norepinephrine (causes the body to have a fight or flight response)
adrenal glands
Our hormones can affect our thoughts and _____.
emotions
