Arthrogyrposis
The Neuromaturation theory
Suggests that development is primarily biologically driven. Believes that environment has little to do with development. Motor delays related to central nervous system.
Muscle problem where one muscle group is firing all the time
Spacticity
Quadriplegia
Complete severation at the cervical spinal level, paralysis in all four limbs (loss of sensation, movement, reflexes)
Paraplegia
Complete severation at the thoracic level, paralysis in the legs. (spinal cord injuries)
What are the major purposes of the cerebellum?
To assist in maintenance of muscle action, and receive and integrate all sensations received from the sensory systems. Promote consistent and smooth activation and control between paired agonist and antagonist muscles.
What happens with Asthenia?
Skeletal muscles tire quickly after minor activity
What is apraxia?
A disorder of motor planning, or difficulty carrying out non-habitual, purposeful movement. Damage to cerebrum. They appear to be clumsy and poorly coordinated, particularly when learning new motor task.
How does memory work?

Peripheral level of memory, limitless capacity
Short-term sensory
Mid range memory, limited capacity of 7 items for 30-60 seconds
short-term memory
Memory with Unlimited capacity, can stay permanently
Long-term memory
The vestibular system
Located in the inner ear, stimulated in response to gravity. Normal vestibular function facilitates balance and equilibrium, stabilization of the eyes when the head if moving, and enhanced sensory organization.
What happens when the vestibular system is damaged?
abnormal muscle tone, limited postural security and postural control, poor balance, poor eye pursuit, seeking or avoiding swinging/spinning, and motion sickness.
