Nervous System
3 main functions of the nervous system in humans
Sensation, Integration, Response
Three types of muscles
skeletal, smooth, cardiac
Which gland is located in the brain and controls the Endocrine System.
Hypothalamus
Functions of the Muscle System
heart, bones, vessels
The point of contact between neuron-neuron, neuron-other cell
a Synapse
Factors that are thought to prevent a CNS from regenerating its damaged axon
What is usually more than one neuron involved and pesky astrocytes (they produce produce chemicals that limit regeneration and also produce scar tissue)
Common muscle injuries
Hamstring Strain, Quadriceps Muscle Contusion, Calf Strain, Groin Strain.
These organs or glands in the Endocrine system are affected by the Cushing's Syndrome.
Pituitary and Adrenal glands
What is Smooth Muscle
A type of muscle that contracts without any voluntary control
What is a nerve impulse and why is it important?
the neuron responding to a stimulus and its important because this leads to a Synapse
The function of a neuron and its three main parts
What is transport and process input and cause output 1- cell body 2- dendrites 3- axon
What is Cardiac Muscle
a specialized, organized type of tissue that only exists in the heart.
These four rice sized glands that control your body's calcium level.
the Parathyroid
What is the definition of Muscle System
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles.
Nissell bodies breakdown, cell body increases in size, nucleus decentralizes.
Chromatolysis
A Synaptic Cleft
a fluid filled space between the pre-synaptic and post-synaptic membranes.
Which muscle flexes your forearm?
The bicep bronchi
What two glands control the direction of hormones during homeostasis.
the Hypothalamus and Pituitary glands
Name the two muscles that you just located, that are involved in clenching your teeth:
the temporalis, masseter
part of the cell body bundles of intermediate filaments (neurofilaments) important in maintaining cell shape and integrity
a Neurofibril
Where all our higher order functions occur and what give 3 examples of these functions.
Central Nervous System. Memory, judgement, intelligence.
Which muscle extends the head?
trapezius muscle
This other hormone helps the Secretin Hormone.
the Tokinin Hormone
Which muscle flexes the head?
sternocleidomastoid muscle
Outer layer, formed by the neurolemmocyte, that wraps the axon of a PNS neuron
Neurilemma
