Q3 L01 - why study the brain and the nervous system
This document discusses the brain and nervous system. It explains that the nervous system is responsible for sending, receiving, and processing nerve impulses throughout the body to allow organs and muscles to function. Neurons are the basic building blocks and carry information through dendrites to the cell body and down the axon through terminal buttons. Neurotransmitters are released at synaptic terminals to communicate between neurons and turn cells on or off through excitatory or inhibitory signals. Major neurotransmitters discussed include acetylcholine, dopamine, GABA, serotonin, and endorphins which impact functions like movement, learning, mood, and pain perception.
Biological Processes 2009
The central nervous system is composed of the brain and spinal cord. The spinal cord contains sensory neurons, motor neurons, and interneurons that enable spinal reflexes, allowing the body to quickly remove itself from danger. The peripheral nervous system includes the autonomic nervous system, which regulates internal organs, and the somatic nervous system, which connects the brain to skeletal muscles. Neurons transmit electrochemical signals via neurotransmitters released at synapses between neurons.

Nervous
The nervous system consists of the brain, spinal cord, and nerves. It has three major functions - to receive and process sensory information, control responses to this information, and coordinate voluntary and involuntary actions. It has two main divisions - the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves). The basic functional unit of the nervous system is the neuron, which transmits electrochemical signals.
Psychology
This chapter discusses the biological basis of behavior, focusing on the nervous system and endocrine system. It describes how neurons communicate via electrical and chemical signals to coordinate the body's functions. Specific areas of the brain like the limbic system and cerebral cortex each have roles in functions like memory, emotion, language, and movement. Genes and evolution also influence behavior, as seen through studies in behavior genetics and evolutionary psychology.
The Peripheral Nervous System
The central nervous system (CNS) is the primary control center of the body and is composed of the brain and spinal cord. The CNS processes and guides movement and sends/receives sensations throughout the body via the peripheral nervous system (PNS). The PNS connects the CNS to sensory receptors and allows it to pick up external information and control skeletal muscles. Together the CNS and PNS work to regulate, control, and coordinate all neural impulses, thoughts, and feelings in the body.
nervous system
The document discusses the nervous system, including its key components and functions. It describes:
- The central nervous system (CNS), made up of the brain and spinal cord, and the peripheral nervous system (PNS), consisting of nerves that connect to organs.
- How neurons transmit signals via electrical and chemical synapses, aided by glial cells. The PNS has somatic and autonomic divisions, with the latter regulating involuntary functions.
- Common nervous system disorders include infections, injuries, degeneration and functional issues presenting with headaches, weakness and sensory changes. Neurologists and neurological surgeons treat such conditions.
Peripheral Nervous System
The nervous system comprises the central nervous system (CNS) and peripheral nervous system. The CNS includes the brain and spinal cord, which control the mind and behavior. The peripheral nervous system has two divisions - the autonomic nervous system which regulates involuntary functions, and the somatic nervous system which controls voluntary skeletal muscle movement. Neurons are the basic functional units of the nervous system, sending and receiving electrochemical signals that allow for sensory input, integration of information, and motor output.
Nervous system
The nervous system has three main functions: receiving information, interpreting information, and making the body respond. It is divided into the central nervous system (brain and spinal cord) and peripheral nervous system (nerves throughout the body). The peripheral nervous system is further divided into the somatic nervous system (controls voluntary muscles and skin sensation) and autonomic nervous system (controls involuntary functions like heart rate through the sympathetic and parasympathetic divisions). Neurons are the basic functional units and transmit signals through electrical and chemical processes. Common nervous system ailments include multiple sclerosis, polio, brain tumors, meningitis, rabies, stroke, and encephalitis.
Nervous System
The nervous system controls and coordinates the body's activities and consists of the central nervous system and the peripheral nervous system. The central nervous system is comprised of the brain and spinal cord. The peripheral nervous system consists of nerves that connect to the central nervous system and transmit signals between different parts of the body. The nervous system has sensory neurons that receive stimuli and motor neurons that send signals to muscles and glands to respond.

Nervous system physiology.pdf
This document provides an overview of the human nervous system, including:
- The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system (PNS) includes nerves connecting the CNS to muscles and sensory organs.
- The nervous system has sensory, integrative, and motor functions. Sensory neurons detect stimuli and send signals to the CNS. The CNS integrates these signals and directs motor neurons to respond.
- Neurons are the basic functional units and come in various types. They are supported by glial cells like oligodendrocytes and astrocytes. The CNS is protected by meninges and cerebrospinal fluid.

Benefits and challenges of using oer
This document discusses the benefits and challenges of using open educational resources (OER). It begins by defining OER as freely available online teaching and learning materials. The main benefits outlined are that OER are free, accessible online, convenient to use without physical textbooks, and provide a large quantity of material on many topics. However, some challenges of OER are that some students prefer printed materials, it can be harder to comprehend materials online, using e-readers before bed may disrupt sleep, and it takes time to sift through large amounts of material to find high quality resources. The conclusion is that using a mix of OER electronic materials and traditional printed textbooks may be best.
The Brain

It covers topics like neurons, the central and peripheral nervous systems, the hindbrain, limbic system, cerebral cortex, left and right hemispheres, and how hormones interact with the nervous system. It provides details on how psychologists study the brain using techniques like EEG, CT, MRI, and PET scans. It also discusses language processing areas and higher cognitive functions localized to different cortical regions.
SPSCC poster presented at WPA
This study examined the relationship between gender identity and altruistic behavior, as measured by donations to charity. 471 college students completed a survey to determine their gender identity as masculine, feminine, androgynous, or undifferentiated. They were then given the option to donate a $5 gift card to a food bank or keep it. While gender identity overall did not predict donations, those with a feminine identity donated more than those who were undifferentiated. The results provide partial support for the hypothesis but also indicate limitations in using the outdated measure of gender identity employed. Further research is needed using improved measures and additional variables.

The Nervous System
The document discusses the biological perspective and structure of the nervous system. It covers key topics like:
1. The central nervous system including the brain and spinal cord, and the peripheral nervous system which connects the CNS to the senses and body.
2. How neurons use neurotransmitters to communicate via synaptic transmission between neurons in either an excitatory or inhibitory manner.
3. The autonomic nervous system which controls involuntary functions and is divided into the sympathetic and parasympathetic nervous systems that work in opposition to activate the fight or flight response or rest and digest responses.
