|
What is the function of a neuron? |
performs all communication information processing and control functions |
|
|
What are the functions of a Neuroglia? |
Preserves the physical biochemical structure of neural tissue, separates and protects neurons, provides support framework for neural tissue, acts as phagocytes & helps regulate composition of interstitial fluid |

Nervous System |
|
|
What organs are in the Nervous System? |
Brain, spinal cord, receptors in complex sense organs (eye & ear), nerves that link the nervous systems with other systems |
|
|
The central nervous system contains? |
The brain and spinal cord |
|
|
The functions of the Central nervous system? |
Integrating, processing coordinating sensory data FROM the peripheral receptors and sends out motor commands |
|
|
The CNS, specifically the brain is also the seat of? |
Higher functions such as intelligence, memory, learning and emotion |
|
|
The Peripheral Nervous System contains? |
Neural tissue outside the CNS |
|
|
Functions of the peripheral nervous system? |
Delivers sensory info to the CNS carriers motor commands to peripheral tissue and organs |
|
|
PNS / 2 = ? |
Afferent and Efferent Divison |
|
|
Afferent Divison? |
The PNS brings sensory info to the CNS from receptors in peripheral tissues and organs (sensory input) |
|
|
Receptors are part of? |
PNS, afferent divison |
|
|
What are receptors ? |
sensory structures that either detect change in the environment (internal/external) |
|
|
Efferent Divison? |
can be broken down in to somatic and automatic nervous system |
|
|
The Somatic Nervous System is part of? |
The PNS Efferent division |
|
|
The SNS controls? |
Skeletal muscles contractions, which are voluntary contractions under subconscious control |
|
|
The Autonomic Nervous system is part of the? |
PNS efferent division |
|
|
The autonomic Nervous system regulates? |
smooth/cardiac muscle and glandular secretions |
