What else can I help you with?
What are impulses?
Impulses are brief electrical signals that transmit information within the nervous system. They travel along the axon of a neuron and are crucial for communication between different parts of the body. Impulses can trigger various physiological responses, such as muscle contractions or the release of hormones.
One that carries impulses between the periphery and CNS areas is called?
A neuron. Neurons are specialized cells that transmit electrical signals in the form of nerve impulses. They play a critical role in transmitting information between the peripheral nervous system and the central nervous system.
A negative emotional state caused by having to choose between two or more incompatible goals or impulses is called?
Cognitive dissonance.
What does the prefix ego mean?
The prefix "ego" comes from Latin and means "I" or "self." It is used in psychology to refer to the conscious part of the mind that experiences reality and mediates between the primitive impulses of the id and the moralizing conscience of the superego.
Is muscle memory real?
Yes, but the memory is not in the muscles themselves, it is in the nervous system. A more correct name for it might be "learned reflexes" because this form of memory/learning happens well below the level of consciousness, near the level of the reflexes.
Which structure conducts nerve impulses between gyri in different hemispheres of the cerebrum?
Corpus callosum
Which cerebral white matter structure conducts nerve impulses between gyri in different hemispheres o?
The corpus callosum is the cerebral white matter structure that conducts nerve impulses between gyri in different hemispheres of the brain. It is responsible for communication and coordination between the left and right hemispheres.
The difference between the brain and the spinal cord?
brain controls perception,reflexes,emotionsbehavioral sequences,etc. spinal cord helps in transmission of neural inputs between periphery and brain
Which tissue type conducts impulses?
Nerve cells, neurons, are designed to conduct electrical impulses, passing messages between the nerves and other tissues. For example, one impulse is sent to the brain signaling pain when you burn your hand and than another message telling your hand to move off the stove.
What type of tissue receives sensory input integrates data and conducts impulses?
The type of tissue that receives sensory input, integrates data, and conducts impulses is nervous tissue. Composed of neurons and glial cells, nervous tissue is responsible for transmitting electrical signals throughout the body, facilitating communication between different systems. Neurons detect stimuli, process information, and send impulses, while glial cells support and protect the neurons. This tissue is essential for coordinating responses and maintaining homeostasis.
What is a specialized cell that conducts impulses through the nervous system?
The specialized cell that conducts impulses through the nervous system is called a neuron. Neurons are the building blocks of the nervous system and are responsible for transmitting electrical and chemical signals throughout the body to enable communication between different parts of the body.
Is there a relationship between the type of information conveyed by an axon at the speed at which it conducts impulses?
Yes, there is a relationship between the type of information conveyed by an axon and the speed at which it conducts impulses. Axons that transmit information related to motor functions or sharp pain tend to be myelinated and larger in diameter, allowing for faster impulse conduction. In contrast, axons conveying less urgent sensory information, such as dull pain or temperature, are typically smaller and may be unmyelinated, resulting in slower conduction speeds. This differentiation helps the nervous system prioritize and respond to various types of stimuli efficiently.
What arenerve impulses?
Nerve impulses, also known as action potentials, are electrical signals that travel along the axons of neurons. They are generated when a neuron is stimulated past a certain threshold, causing a rapid change in the electrical charge across the cell membrane. This change propagates along the neuron, allowing communication between nerve cells and facilitating processes such as muscle contraction, sensory perception, and reflexes. The transmission of nerve impulses is essential for the functioning of the nervous system.
What is the function and organs of the nervous system?
Once this matter is complex and requires a detailed answer, which implies a long writing, I understand that it is more convenient that you visit the link placed right below.However, not to let you without an answer here, these are the major divisions of the vertebrates' nervous system along with its functions.Central Nervous System > Brain and spinal cord / Integrated and control centers.Peripheral Nervous system (PNS) > Central Nerves and spinal nerves/ Communicaton lines between the CNS and the rest of the bodySensory (afferent) division > somatic and visceral sensory nerve fibers / Conducts impulses from receptors to the CNSMotor (efferent) division > motor nerve fibers / Conducts impulses from the CNS to effectors ( muscles and glands)Sympathetic division > Mobilizes body systems during activity (fight or flight)Autonomic nervous system (ANS) > visceral motor (involuntary)/ conducts impulses from the CNS to cardiac muscles, smooth muscles, and glands.Somatic nervous system> Somatic motor ( involuntary)/Conducts impulses from the CNS to skeletal muscles
To which locations on the axon do impulses jump?
Impulses jump between the nodes of Ranvier on the axon.
Which of the spinal cord and nerves is the conducts nerves impulses?
The spinal cord and nerves both play crucial roles in conducting nerve impulses. The spinal cord serves as the main pathway for transmitting signals between the brain and the rest of the body, facilitating reflex actions and sensory information processing. Nerves, which branch out from the spinal cord, carry these impulses to and from various body parts, ensuring communication between the central nervous system and peripheral areas. Together, they enable coordinated movement and sensory perception.
What kind of tissue conducts messages from one part of your body to another?
Nervous tissue conducts messages (nerve impulses) throughout the body. It is made up of neurons that transmit electrical signals and support cells called glial cells. This allows for rapid communication between different parts of the body.
