Is the nervous system on the AP bio test?

Is the nervous system on the AP bio test?

Nervous System : Example Question #2 There are myriad dendrites on each neuron that then propagate this signal to the soma (or cell body), allowing the signal to be passed down the axon to another neuron.

Is a 5 on AP bio good?

AP Biology is one of the more difficult APs based on its challenging curriculum, the low rate of students who earn 5s on the exam, and the consensus from students on the demanding nature of the class. Ideally, you should take an Intro to Biology class before you take AP Biology so that you’re fully prepared for it.

What is the unit of nervous system Mcq?

neurons
The unit which make up the nervous system are called neurons.

Which of the following best describes the order of information processing in a neuron?

Which of the following best describes the order of information processing in a neuron? Explanation: A neuron receives input from other neurons at the dendrites. Neurotransmitters released by other neurons bind to receptors on the dendrites, which carry the signal to the cell body.

Are responsible for myelination quizlet?

Which of the following cell types in the central nervous system are responsible for myelination? Schwann cells are the myelination cells of the peripheral nervous system, and thus (d) is the correct answer.

Are oligodendrocytes myelinated?

Oligodendrocytes are the myelinating cells of the central nervous system (CNS). They are generated from oligodendrocyte progenitor cells following tightly orchestrated processes of migration, proliferation and differentiation [1].

What are the 4 main parts of a neuron?

A neuron has 4 basic parts: the dendrites, the cell body (also called the “soma”), the axon and the axon terminal. Dendrites – Extensions from the neuron cell body that take information to the cell body. Dendrites usually branch close to the cell body.

Which is a nervous system test?

A neurological exam, also called a neuro exam, is an evaluation of a person’s nervous system that can be done in the healthcare provider’s office. It may be done with instruments, such as lights and reflex hammers. It usually does not cause any pain to the patient.

Why is white matter white?

White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.

What are the four physiological events promoted by the sympathetic nervous system?

Describe four physiological events promoted by the sympathetic nervous system that would help you cope with a frightening situation. Pupils dilate, heart increases, lungs dilate, and digestion slows. Prepares you for fight or flight.

How do vesicles release neurotransmitters into the synapse?

Vesicles with neurotransmitters in the pre synaptic knob release neurotransmitters into the synapse. They bind to receptors on post synaptic neurons. Describe four physiological events promoted by the sympathetic nervous system that would help you cope with a frightening situation. Pupils dilate, heart increases, lungs dilate, and digestion slows.

How does the parasympathetic nervous system help you come back from scare?

Describe four physiological events that are the parasympathetic nervous system will provide to help you come back from your scare. Heart rate decreases lungs, constrict digestion, resumes when you sleep.
