Answer;
-Projection level
-Projection level controls intermediate relay for incoming and outgoing neurons.
Explanation;
The levels of motor control include; segmental level, projection level and precommand level.
-The segmental level is the lowest level of motor hierarchy. It consists of segmental circuits of the spinal cord, Its circuits control locomotion and specific, oft-repeated motor activity. These circuits are called central pattern generators (CPGs).
The projection level consists of: Cortical motor areas that produce the direct (pyramidal) system, and Brain stem motor areas that oversee the indirect (multineuronal) system
. It helps control reflex and fixed-pattern activity and houses command neurons that modify the segmental apparatus.
Precommand level; Cerebellar and basal nuclei systems that:
-Regulates motor activity, precisely start or stop movements, coordinate movements with posture, Block unwanted movements
, and Monitor muscle tone.
Answer:
If the scull is fused the individual is not a baby
Explanation:
If a skull is found, one of the first things to do is classify by age. Careful observation will show that the skull may or may not be fused. Noteworthy observations could give the professional an idea of the individual's age.
In the womb when the bones of the skull are being formed thre are typically seven bones with gaps in between. This allows the infant to pass safely through the birth canal but giving way to squeezing and the contractions of the uterus. After the child is born there are still remaining gaps. These gaps allow the brain to grow and develop without pressure from the skull. This can often be observed by a soft spot on the top of the infant's head sometimes called a "mole"
Around two years of age, these bones begin to fuse and harden. Therefore if a skull is found with fused bones, the individual can be placed to be older than two years of age. Other determining factors such as teeth etc can narrow down the individual's age.
