One of the four major portions of the brain; surrounds third ventricle
Diencephalon
What is the order of the meninges?
Dura mater, arachnoid, and pia mater
What lobe is responsible for problem solving?
Frontal
What are sensory receptors?
Gather information and convert it into nerve impulses
What are pons?
Helps the brain and spinal cord communicate and responsible for breathing rates
In the diencephalon, links the endocrine to the neural systems
Hypothalamus
The ____________ is considered the autonomic control center of the body due to its regulation of hormonal secretion and heart rate.
Hypothalamus
The nervous system sends information via a network of cells using electrical signals called ____________ .
Impulses

Increase surface area
What is the cerebrum?
Largest part of the brain
What is diencephalon?
Lies between the cerebral hemispheres and above the membrane
Comprised of parts of the cerebral cortex, diencephalon, and other deep nuclei, the ____________ represents the area of emotional control.
Limbic System
What is the hypothalamus?
Links endocrine and nervous system
What is the PNS?
Made up of nerves
What is the function of the hypothalamus?
Maintains homeostasis
In the brainstem, controls vital visceral activities
Medulla oblongata
What are meninges?
Membranes that cover and protect the brain and spinal cord
What is the function of the cerebellum?
Motor coordination and balance
What is the nervous system composed of?
Neurons and neuroglia
Lobe responsible for visual
Occipital
What lobe functions in information processing, cognition, and speech?
Parietal
In the brainstem, helps maintain breathing
Pons
What is the function of the cerebrum?
Reasoning, memory, and voluntary responses
The ____________ is the alert system of the body because of the tracts that provide communication between lower and higher brain regions.
Reticular formation
What are gyri?
Ridge or convolution on the surface of the brain

Right side
What are ventricles?
Series of connected cavities within the cerebral hemispheres and brain stem
Motor functions can be divided into ______ and ______ nervous systems.
Somatic and Automatic
The ____________ provides two-way communication between the central nervous system and the peripheral nervous system.
Spinal Cord
What lobe stores memory?
Temporal
In the diecephalon, is a relay area for sensory impulses

Thalmus
What is the cerebral cortex?
Thin layer of gray matter
What is the arachnoid?
Thinnest layer of meninges that does not have its own blood vessels
What is the dura mater?
Though covering over entire brain
What is the function of the medulla oblongata?
Transmits ascending and descending impulses between the brain and the spinal cord
What is integrative function?
When sensory impulses are brought together and create sensation, add to memory or produce thought in the brain
What is the correct order of meninges from superficial to deep?
dura mater, arachnoid mater, pia mater
By initiating responses to these changes in the body, the nervous system works to maintain ____________ .
homeostasis
