What is the central nervous system composed of quizlet?
The central nervous system is composed of: The brain and spinal cord. The peripheral nervous system is composed of: The cranial and spinal nerves that travel to all parts of the body.
Where is the central nervous system located in the brain?
It’s the top part of the brainstem, which connects the brain to the spinal cord.
Is the brainstem part of the central nervous system?
The brainstem is the stalklike part of your brain that connects your brain to your spinal cord (column of nerve tissue that runs down your spine). It sits toward the bottom of your brain and is part of your central nervous system.
Which neurons are present in central nervous system?
Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
What does central nervous system consist of what does it control?
The central nervous system (CNS) is comprised of the brain and spinal cord. The three broad functions of the CNS are to take in sensory information, process information, and send out motor signals.

What are the two parts of the central nervous system quizlet?
The CNS consists of only two parts – name them. The CNS is divided into the brain and spinal cord. The PNS can be divided into two parts – name them.
Which part of the body is the control center for the nervous system?
The brain
The brain and spinal cord (the CNS) function as the control center. They receive data and feedback from the sensory organs and from nerves throughout the body, process the information, and send commands back out.
Which is a function of the central nervous system quizlet?
The main functions of the central nervous system is to PROCESS information received through sensory systems and other parts of the body and to activate appropriate actions to the external/internal stimuli.
Which is not part of the central nervous system?
Answer and Explanation: The d. Neuronal cell body of a sensory afferent is not part of the central nervous system. Sensory afferent nerves are located in the peripheral nervous system.
What are the 7 main parts of the central nervous system?
The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
What are the 3 functions of the central nervous system?
What is the central nervous system in psychology?
The central nervous system (CNS) is comprised of the brain and spinal cord. The three broad functions of the CNS are to take in sensory information, process information, and send out motor signals. The CNS receives sensory information from the nervous system and controls the body’s responses.
What is the main function of our nervous system psychology quizlet?
Transmits information from the brain to the Somatic Nervous System which activates motor neurons to which muscles respond. Making decisions, judgements, organising, planning, problem solving, attention, expression of emotional behavious, personality.
What are the main functions of the central nervous system quizlet?
What is the main control center of the central nervous system?
The brain is the control center of the nervous system. It’s like the pilot of a plane. It tells other parts of the nervous system what to do. The brain is also the most complex organ in the body.
Which statement best describes the central nervous system?
Which best describes the central and peripheral nervous systems? The central nervous system processes stimuli information the body receives, and the peripheral nervous system senses stimuli and carries out the reaction.
What is the central nervous system main function?
Most systems and organs of the body control just one function, but the central nervous system does many jobs at the same time. It controls all voluntary movement, such as speech and walking, and involuntary movements, such as blinking and breathing. It is also the core of our thoughts, perceptions, and emotions.
What are the four major components of the central nervous system?
The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells).
…

- 8 cervical nerves.
- 12 thoracic nerves.
- 5 lumbar nerves.
- 5 sacral nerves.
- 1 coccygeal nerve.
What cells are part of the central nervous system?
Main. The central nervous system (CNS) is now thought to consist of three main cell types: neurons, glial cells and vascular cells.
What are 3 main parts of nervous system?
The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system.
What are the 5 main parts of the nervous system?
The PNS is broken into the somatic nervous system and the autonomic nervous system.
- Somatic Nervous System. The somatic nervous system is made up of motor neurons and sensory neurons that help the body perform voluntary activities.
- Autonomic Nervous System.
- Sympathetic Nervous System.
- Parasympathetic Nervous System.
What are the parts and functions of the central nervous system?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What are the main organs parts involved in the CNS?
The brain and spinal cord are the organs of the central nervous system. Because they are so vitally important, the brain and spinal cord, located in the dorsal body cavity, are encased in bone for protection. The brain is in the cranial vault, and the spinal cord is in the vertebral canal of the vertebral column.
