Skeletal
A place in the body where 2 or more of your bones come together
Joint
Slight tension in the muscle
tone
Most basic unit of the nervous system
neuron
What are 2 common muscle injuries?
strain
tendonitis
What are the 3 functions of the skeletal system?
support/protection
movement
storage and production of materials
Supportive tissue that is softer and more flexible than bone
Cartilage
Attaches muscle to bone
tendon
A part of the brain that consists of several specialized areas of the brain. These areas are responsible for receive messages from sense organs, controlling movement, memory, communication and reasoning
cerebrum
What are 2 common joint injuries
sprain
dislocation
overuse
torn cartilage
What are the 2 divisions of the Peripheral Nervous System
sensory
motor
Bands that hold bones together with joints
Ligament
Muscle weakens over time due to lack of use
atrophy
A thick column of nerve tissue that links the brain to most of the nerves in the PNS
spinal cord
What are 3 injuries/infections of the nervous system?
concussion, paralysis, meningitis, carpal tunnel
What are the 3 components that make up our Central Nervous system
brain
spinal cord
reflexes
Overstretched or torn ligament
Strain
“Pulled” muscle
strain
Automatic response to your environment
reflex
What is the difference between a simple fracture and a compound fracture
compound the bone pierces the skin
What are the 3 types of neurons?
sensory
interneurons
motor
Process is which cartilage is replaced by bone, making the bone stronger
ossification
Overuse of tendons that can lead to pain and swelling
tendonitis
This part of the brain coordinates movement and helps balance
cerebellum
What are 2 activities in which fine motor skills are used? What are 3 activities in which gross motor skills are used?
fine - writing, grabbing, scissors, wavining
gross - running, jumping, walking, throwing, catching
Explain what Smooth muscle, Cardiac muscle, and Skeletal muscle do for you
smooth - involuntary movements within body
cardiac - heart
skeletal - voluntary movement
