Questions and Answers

Match each type of nerve with its primary function:

Nerves that connect directly to the brain or spinal cord = Relay sensory information and motor commands involved in reflexes Nerves carrying information from the brain and spinal cord to the rest of the body = Enable voluntary movements and transmit signals to organs and muscles Sensory nerves in the skin = Detect stimuli such as pressure, pain, temperature, and texture Nerves within muscles = Help maintain posture and coordinate movements by sensing muscle length and tension

Match each type of sensory receptor in the skin with the sensation it primarily detects:

Touch receptors = Respond to pressure and texture Temperature receptors = Detect changes in heat and cold Pain receptors = Signal tissue damage or excessive pressure Pressure receptors = React to how hard, soft, rough, or smooth an object is

Match each part of the tongue with its role in taste perception:

Taste buds = Contain specialized cells for detecting different taste qualities Receptors = Respond to specific chemical compounds that correspond to taste qualities Nerves = Transmit signals from the taste receptors to the brain Brain = Processes and interprets signals from the taste nerves to perceive flavors

Flashcards

Senses

Animals use them to obtain and process information about their environment.

Skeletal system

A system mainly made of bones that gives structure, support, and protection to the softer parts of the body.

Brain

The central processing organ protected by the skeletal system, part of the nervous system.

Spinal Cord

Bundle of special nerve fibers and tissue that connects almost all parts of the body to the brain, protected by the backbone. Part of central nervous system.
