Hand Control During Infancy and Toddlerhood01:31

Hand Control During Infancy and Toddlerhood

Hand movements during infancy and toddlerhood develop from broad, relatively uncontrolled actions into increasingly precise fine motor skills. This progression depends on nervous system maturation, improved muscle control, and repeated interaction with objects. Early reflexive movements gradually give way to intentional reaching, grasping, object manipulation, and tool use.Early Grasping SkillsNewborns show a strong palmar grasp reflex, automatically closing their fingers when the palm is...
Principles of Development01:31

Principles of Development

Physical development during the prenatal period and early childhood follows two major directional principles: cephalocaudal and proximodistal development. These general patterns happen simultaneously and help explain changes in body proportions and the gradual development of motor skills.Cephalocaudal DevelopmentThe cephalocaudal principle describes development from the head downward toward the lower body. During prenatal development, the head and brain structures develop rapidly before many...
Hierarchy of Motor Control01:18

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Motor and Sensory Areas of the Cortex01:14

Motor and Sensory Areas of the Cortex

The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Somatosensation01:33

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
Motor Skills Development During Early Childhood01:30

Motor Skills Development During Early Childhood

Early childhood is a period of rapid motor development in which children refine gross and fine motor skills. These abilities increase independence and support social interaction, play, and learning.Gross Motor SkillsGross motor skills involve coordinated movements of large muscle groups, including running, jumping, and climbing. By about 2.5 years, most children can jump with both feet. Hopping, which requires greater balance and strength, usually emerges around age 4.Stair climbing also...
