Biological Influences Flashcards
Subdivisions of the human nervous system
-Central nervous system
-Peripheral nervous system
Subdivisions of the CNS
-Brain
-Spinal cord
Subdivisions of the PNS
Somatic & autonomic nervous system
Subdivisions of the autonomic nervous system
Sympathetic & parasympathetic nervous system
Central nervous system (CNS)
Receives and transmits information to and from the peripheral nervous system
Brain
The largest part of the CNS and is the command and control centre of humans
Spinal cord
-Receives information from the peripheral nervous system and transmits it to the CNS
-Receives information from the brain and sends it to other parts of the body via the peripheral nervous system
Peripheral nervous system (PNS)
Transmits messages to and from the central nervous system
Somatic nervous system
Receives sensory information from organs such as the skin, ears and eyes, and communicates information via the sensory nerves to the CNS and motor messages from the CNS to skeletal muscles
Subdivisions of the autonomic nervous system
The sympatheic & parasympathetic nervous system
Autonomic nervous system
A network of neurons that transmit messages between the brain and the smooth muscles found in the heart, lungs, blood vessels and glands via the spinal cord; it is self regulatory
Sympathetic nervous system
Arouses the body to perform, act or react
Parasympathetic nervous system
Calms the body down to conserve energy
Forebrain
The outer brain areas are involved in perception, learning, motor and conceptual activities, while those areas near the centre of the brain are involved in internal and automatic bodily functions such as body temperature, reproductive functions, eating, sleeping and emotions
Cerebrum
Controls motor and mental activity
