Anatomy chapter 14

• Telencephalon
• Diencephalon

• Cerebrum
• Diencephalon

• Metencephalon
• Myelencephalon

• cerebellum and pons
• Medulla oblongata

controls conscience sensations, intellect, memory, complex movement

coordinates movement

contains centers for emotions, autonomic functions, and hormone production

process visual and auditory sensory information

connects cerebellum to the brain stem and controls involved with somatic and visceral motor control

• Relays sensory information to the thalamus
• autonomic functions of heart rate, blood pressure, and digestion

• 1. Dura mater
• 2. Arachnoid
• 3. Pia

cushions delicate structures, support the brain, transports nutrients, chemicals and wastes

• are the most serous and fatal if not treated quickly
• due to arterial bleeding which has vary high pressure causing severe distortion of tissues

causes are from venous bleeding which has much lower pressure

• 1. portions of the hypothalamous (control hormones)
• 2. Capillaries in pineal gland (hormone regulation)
• 3. Capillaries of the posterior pituitary gland (hormones)
• 4. capillaries of the choroids plexus (cell produce CSF)

elevated ridges

shallow depressions

• 1. central sulcus
• 2. Lateral sulcus
• 3. Parieto-occipital sulcus

• 1) each cerebral hemisphere receives sensory info. and sends motor commands to the opposite side of the body
• 2) Each hemisphere has a different function
• 3) Assignment of specific function is imprecise

• 1) associated fibers
• 2) Commissural fibers
• 3) Projection fibers

monitors activity in the primary sensory cortex

receives and analyzes sensory info

where an individual cannot talk or understand the language

Regulates patterns of breathing and vocalization

preforms abstract functions such as predicting consequents of behavior, events or actions

Direct many subconscious activities

establishing emotional states and related behavior drives

Filter sensory info

• 1. subconscious control of muscle contractions
• 2. Control of autonomic function
• 3. Coordinates activity of the nervous and endocrine system
• 4. Secretes hormones
• 5. Produces emotions and behavior drives
• 6. coordinates voluntary and autonomic function
• 7. regulates body temperature

Integrates visual info with other sensory imputes involuntary mote responses

relay auditory info to the thalamus

involuntary control of tone and posture

regulates activity of cerebral nuclei

Autonomic processing of incoming sensations and outgoing motor commands, maintains conscience

connects primary motor cortex with motor neurons in the brain and spinal cord
