Pinky and the Brain
What part of the Nervous system is the brain in?
The CNS
What is the nervous System
The nervous system is a complex network of neurons and support cells that regulates and coordinates body functions.
The neuron is what?
The basic unit of the nervous system is the neuron (nerve cell).
Whats the other name for the Spine
The Vertebral Column
What is the Cerebellum's function
Cerebellum's functions with coordination and balance.
Name a technique used to study the nervous system
Electrophysiology: Recording electrical activity of neurons.
Imaging Techniques: Methods like MRI, fMRI, and PET scans visualize brain structure and function.
Histological Techniques: Examining brain tissue samples under a microscope.
Behavioral Studies: Observing the effects of lesions or pharmacological interventions on behavior.
Do neurons regenerate
Unlike other cells neurons don't easily regenerate.
How many Vertabrae do we have as a kid and Adult
At birth, we have 33 vertebrae, but some fuse together over time, resulting in 26 vertebrae in adults.
What does the brain stem handle
Basic life functions (breathing, heart rate).
What are the two parts of the PNS and what do they do?
Somatic Nervous System: Controls voluntary movements
Autonomic Nervous System – Controls involuntary functions
The axon ends in small bumps near another neuron’s dendrite, with a gap called a
synapse
How many muscles is the Spine supported by
The spine is supported by over 120 muscles, which enable us to move, bend, and rotate.
What is the Cerebrum's functions
Conscious thought, memory, and learning.
How many systems are in the nervous system and what are they
Central Nervous System (CNS): Includes the brain and spinal cord.
Peripheral Nervous System (PNS): Includes the cranial and spinal nerves.
What are Axons covered by?
Myelin Sheath
What 5 sections is the spine divided into
cervical(neck), thoracic(mid back), lumbar (lower back), sacrum (base of spine), coccyx (tailbone),
What lobes are in the brain and what do they do?
(The Frontal, Parietal, Temporal and Occipital lobes)
The Frontal is responsible for reading and decision making
Parietal is responsible for touch and taste
Temporal is responsible for hearing and processing auditory information
The Occipital is responsible for sight and object recognition
What types of cells are found in the nervous system?
There are two primary types of cells:
Neurons: These are the fundamental units of the nervous system that transmit information through electrical and chemical signals. Neurons consist of a cell body, dendrites (receiving signals), and an axon (sending signals).
Glial Cells: Supporting cells that provide structural support, insulation, and nutrients to neurons. Types include astrocytes, oligodendrocytes, Schwann cells, and microghhhhh
What helps messages jump across the synapse to the next neuron.
Nuerotransmitters
Why is the Spine Flexible?
The spine is flexible due to the presence of discs of cartilage between the vertebrae. These discs act as cushions and allow the spine to bend and twist.
