Study Notes
Neurotransmitters and the Nervous System
- Neurotransmitters are released by dendrites.
- Alzheimer's disease is a neurodegenerative disorder of the Central Nervous System (CNS).
- The Peripheral Nervous System (PNS) has two divisions: the Somatic Nervous System and the Autonomic Nervous System, with the latter having two subdivisions: the Parasympathetic Nervous System, which relaxes, and the Sympathetic Nervous System, which acts in stress situations.
Brain Structure and Functions
- The accumulation of neuronal bodies with their dendrites appears gray in color.
- The medulla spinalis is responsible for reflex acts.
- The left hemisphere of the brain controls the right side of the body and vice versa.
- The cerebellum controls learning of balance and coordination.
Neuron Function and Impulse Transmission
- The impulse in a neuron moves in the following order: dendrites → cell body → axon → terminal buttons → other dendrites.
Meninges and Cerebrospinal Fluid
- The meninges are protective membranes of the Central Nervous System.
- The cerebrospinal fluid is located between the arachnoid and pia mater.
- The cerebrospinal fluid protects the Central Nervous System from shocks.
Hormone Regulation
- The hypothalamus controls hormone production and regulates the endocrine system along with the pituitary gland.
- The pituitary gland is the master endocrine gland that regulates other endocrine glands.
Short Answer Questions

- The cerebrospinal fluid protects the Central Nervous System from shocks.
- The hypothalamus controls hormone production and regulates the endocrine system.
- The pituitary gland is the master endocrine gland that regulates other endocrine glands.
Central Nervous System Responses
- The medulla spinalis is responsible for responding to external stimuli, such as avoiding an object.
- The bulbar raquídeo is responsible for regulating heart rate in response to stimuli, such as seeing an attractive person.
- The cerebellum is responsible for coordinating motor responses, such as avoiding an obstacle while biking.
Neuron and Brain Structure
- A neuron consists of a cell body, dendrites, membrane, cytoplasm, nucleus, axon, and terminal buttons.
- The brain consists of the cerebrum, cerebellum, bulbar raquídeo, and mesencephalon.
- The cerebral cortex has folds (circunvolutions) and grooves (sulci).
- The brain stem consists of the midbrain, pons, and medulla oblongata.
- The cerebellum has hemispheres and a vermis.
Inverse Definitions
- A stimulus is a change in external or internal conditions that can be detected by the body.
- White matter consists of axons coated with myelin.
- Microglia are cells responsible for defending the Nervous System.
- A synapse is the connection between two neurons.
